Michael runs 3.5 miles in 30 minutes. If he continues at this rate for 2 hours, determine his rate of change.

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

Can somebody me out with this question

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)
