Question

find the constant rate of change (slope).

Answer 1

Answer:

5

Step-by-step explanation:

The slope is given by

m = ( y2-y1)/(x2-x1)

We can use any two sets of points.  I like to use the first and the last

m = (15-0)/(4-1)

m = (15/3)

   = 5

Answer 2

5 is your answer! it moves 5 up for every 1 right!
