Answer:
1) 1/4
2) 3/5
Step-by-step explanation:
1) The rate of change is basically the slope, and you can find the slope by doing:
change in y/change in x
I started with the point (0,-2) because it's on the line
It goes up 1 and left 4 to get to the second point on the line
So change in y/change in x = 1/4 (this is the rate of change)
2) This is basically the same thing, but you need to do some subtraction.
Change in y = -9-(-3) = -6
Change in x = -5 - 5 = -10
Change in y/change in x = 3/5 (this is the slope or rate of change)
