Point a is at (-6,5) and point m is at (-1.5, -1).
point m is the midpoint of point a and point b.
what are the coordinates of point b?

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
