Tutoring Algebra, slope and intercepts

We looked at slope intercept form and how m is the slope and b is the y- intercept.

To get the y-intercept, you set x = 0
to get the x-intercept, you set y = 0

To get the slope, you use two points (some are easier to work with than others)
x1, y1
x2, y2

Then take (y2 – y1)/(x2 – x1)

Subtracting a negative two is like like adding two

x – – 2 = x +2

If you have the slope and a point, you can plug in the x and y to get the value for b and then complete the equation.
