9-125.

Pick two points on the line and find the change in *y*-values over the change in *x*-values to find the slope.

What do you get? Does this value correspond with a value in the rule above?

Where on the graph does the line cross the *y*-axis?

Also, logically, the graph will cross the *y*-axis when *x* = 0.

Using the rule, can you calculate this value?

What do you get? Does this value correspond with a value in the rule above?
