answer:
-13/12
Step-by-step explanation:
use the formula to find slope using points
it is: y2-y1/x2-x1
plug in point values into formula
-3 = x1. 9 = x2
-2= y1. -15 = y2
-15-(-2)/ 9-(-3)
-13/12
the bottom of the pool is 15 x 30 = 450 sq feet.
you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet
then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet
for a total of 450 +300 +150 = 900 square feet
1 can covers 250 sq ft
so 900/250 = 3.6
so you would need 4 cans of paint
