”It’s for Halving Fun!”

The slope intercept form is probably the most frequently used way to express equation of a line. To be able to use slope intercept form, all that you need to be able to do is:

1) find the slope of a line and
2) find the y-intercept of a line

In general, the slope intercept form assumes the formula:

y = mx + b

Where:

m: is the slope; ‘m’ means ‘move’
b: is the y-intercept; ‘b’ means ‘where the line begins’

The Equation of a vertical line is x = b.

Since a vertical line goes straight up and down, its slope is undefined. Also, the x value of every point on a vertical line is the same. Therefore, whatever the x value is, is also the value of 'b'.

The equation of a horizontal line is y = b where b is the y-intercept.

Since the slope of a horizontal line is 0, the general formula for the standard form equation , y = mx + b becomes y = 0x +b y = b. Also, since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
