If Tucson’s average rainfall is 10 1/4 inches and Yuma’s is 4 4/5 inches, how much more rain, on the average, does Tucson get than Yuma?

Step-by-step explanation:

If Tucson’s average rainfall is 10 1/4 inches and Yuma’s is 4 4/5 inches, then the difference will give us how much more rain, on the average,Tucson get than Yuma.

We find LCM to get

1. perpendicular

2. parallel

3. perpendicular

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
