a. locate the rise over run between points

b. y2-y1/x2-x1

c. m=slope in y=mx+b

Step-by-step explanation:

a) Use rise over run,

() count how far apart up/down the y's are, and how far apart left/right the x's are

() down in the y's mean it is negative

b) change in y over change in x

() y2 - y1 / x2 - x1

c) find the "m" when it is in slope-intercept form

() y = mx + b
