Acar traveled 48.36 miles in one hour. what was it's average speed per minute?

0.806 miles per minute

There are 60 minutes in an hour, so replace the unit "hour" by 60 minutes and recompute.

... 48.36 mi/h = 48.36 mi/(60 min) = (48.36/60) mi/min = 0.806 mi/min

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).

i think the answer is a.( -3, -1 )
