Answer:

1) y = 5/2x - 3/2

2) y = 2/5x - 4/5

Step-by-step explanation:

(1, 1) and (3, 6)

m = (y2 - y1)/(x2 - x1)

m= (6 - 1)/(3-1)

m= 5/2

y - y1 = m(x - x1)

y - 1 = 5/2(x - 1)

y - 1 = 5/2x - 5/2

y = 5/2x - 3/2

(2, 0) and (7, 2)

m = (y2 - y1)/(x2 - x1)

m= (2 - 0)/(7 - 2)

m = 2/5

y - y1 = m(x - x1)

y - 0 = 2/5(x - 2)

y = 2/5x - 4/5

A square patio has an area of 150 square feet. how long is each side of the patio to the nearest tenth?

Solnce55 [7]

length of each side of the patio to the nearest tenth is 12.247 ft.

<h3>How to find the length of each side of the patio to the nearest tenth?</h3>

given that A square patio has an area of 150 square feet.
