This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:
m=(y2-y1)/(x2-x1)
m=(50-25)/(2-1)=25/1
m=25
So the rate of change is 25 mph
Answer:you didnt add the whole thing what is the following??
Step-by-step explanation:
I would say something along these lines: You are walking along a path, and then someone follows you. You then jog a little faster, but the stalker is coming. You then start to run away from the stalker. You realize that you are taking too long, so you jump on a bicycle. The stalker goes in a bicycle, so you jump onto a moving train to get away from him without stopping.
4-1= 3
3-4= -1 slope= -3
y-4=-3(x-3)
y-4=-3x+9
y=-3x +13
