Answer:

y - 3 = (1/2)(x - 1)

Step-by-step explanation:

As we move from the point (-9,-2) to the point (1,3), x increases by 10 and y increases by 5.  Thus, the slope of this line is m = rise / run = 5/10, or 1/2.

Using info from the 2nd point (1, 3), the equation of this line in point-slope form is

y - 3 = (1/2)(x - 1)
