Find the point-slope equation for
the line that passes through the
points (9,-9) and (-2,13). use the
first point in your equation.
y + [? ] = [ ](x+[ ])

The answer to your question is  y = -2x + 9

Step-by-step explanation:

A (9, 9)

B (-2, 13)

Process

1.- Find the slope

   m =

         m = - 2

2.- Find the line equation

         (y - y1) = m (x - x1)

          y + 9 = -2 (x - 9)               y + ? = [  ] ( x + [ ])

          y + 9 = - 2x + 18

          y = - 2x + 18 - 9

          y = -2x + 9

(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

i dont understand the question? ?
