So you’ll take $11.50-$4.75=$6.75 then you’ll divide this answer by 3 6.75/3=2.25 so it was $2.25 per movie to rent
39) y=20x+175
40) y=20(2)+175, so $215

We can use instead of
any general point (x,y) on the line, and for
the point we are interested in: (11,4)
That way the slope can be written as:

Next we can solve for y if this format is the one your instructor prefers:
