**1x+0y=C**. Another vertical line, one parallel to the first, will still have the form 1x+0y=D.

Since the slope of a vertical line is undefined you can’t write the equation of a vertical line using neither the slope-intersect form or the point-slope form. But you can express it using the **standard form**.

The standard form for linear equations in two variables is **Ax+By=C**. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

**Ax+By=C** . The advantage of standard form is that it accommodates both horizontal lines (A=0) and vertical lines (B=0) . These two equations, both in standard form, represent the same line. …

Recall that the slope-intercept form of a line is: **y = mx + b**. To change this into standard form, we start by moving the x-term to the left side of the equation. This is done by subtracting mx from both sides. We now have the equation, -mx + y = b.

Standard form is just another way to write a **linear equation equation** along with slope intercept form and point slope form. The constants, A, B, and C, must be integers. And A must be positive. An example of a line in standard form would be: 4x+7y=12 Here, 4, 7, and 12 are all whole numbers, and 4 is positive.

In summary, a standard equation is set up like this: **Ax + By = C** (where A, B, and C represent numbers). To find the slope (or the rate at which something changes) you must divide the value of A by the value of B (A / B).

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. **1.98 ✕ 10¹³**; 0.76 ✕ 10¹³ are examples of numbers in standard form.

The standard form is just another way to write this equation, and is defined as **Ax + By = C**, where A, B, and C are real numbers, and A and B are both not zero (see note below about other requirements). As you will see in the lesson below, every line can be expressed in this form.

Equation: y=3x+4 You must subtract 3x from both sides. The standard form will be **-3x+y=4**.

Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as **Ax+By=C**. You can also change slope-intercept form to standard form like this: Y=-3/2x+3.

Vertical line would be parallel to y- axis, hence its equation would be **x= c** . The slope of vertical line is undefined, hence there is no point slope form as such.

Vertical Line Equations Vertical lines have equations that look like this: **x=b where b is a real number**. In this equation, b is the fixed value that x must take, despite the varying y-values.

In general, Slope Intercept form is y = mx + b. However, a vertical line has an undefined slope . They also do not have a y-intercept, because they run parallel to the y axis. Therefore, the general formula for a vertical line is **x = x1**.

To convert from slope intercept form y = mx + b to standard form **Ax +** By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.

An undefined slope indicates that we have a vertical line parallel to the y-axis and passing through all points in the plane with an x-coordinate = constant ( c) The equation is written in the **form x = c**. In this case the line passes through (-2 ,-6) and therefore the constant is the value of the x-coordinate.

Another name **for “Scientific Notation**“, where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit), Followed by: ×10 to a power that puts the decimal point back where it should be.

/ˈstæn.dɚd ˌfɔːrm/ (also standard index form) **a way of writing a very large number with one number before the decimal point, multiplied by a power of 10**. For example, 280,000 is 2.8 × 105.

Therefore, 18/45 expressed in standard form is **2/5**.

Lesson – Place Value. Place Value. **When a whole number is written using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9**, it is said to be in standard form. The position of each digit determines the digit’s place value . A place value chart names each place value.

standard form is the usual way of writing numbers in decimal notation, i.e. **standard form = 876**, expanded form = 800 + 70 + 6, written form = eight hundred seventy six.

A vertical line is **a line, parallel to y-axis and goes straight, up and down**, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.

Vertical lines are said to have **“undefined slope**,” as their slope appears to be some infinitely large, undefined value. See the graphs below that show each of the four slope types.

- This will result in: y=2x−4 .
- When x=0 , y=−4 .
- The slope is basicly the constant infront of the x (when simplified to the y=ax+b ).

The equation y = 2x + 6 is in slope-intercept form, so we know that the slope is equal to the coefficient of x, which is **2**, and the y-intercept is equal to the constant term, which is 6. Thus, we have that the slope of y = 2x + 6 is 2, and the y-intercept is 6.

If the equation of a line is in standard form, the easiest method to graph the line is by **finding intercepts**. Remember that at the y-intercept, the x coordinate is equal to 0, and that at the x-intercept, the y coordinate is equal to 0. To find the y-intercept, set x equal to 0 and solve for y.
