The expression 100 + 20m, gives the volume of water in eduardo's pool (in liters) after eduardo spends m minutes filling his pool. what is the volume of water in eduardo's pool after he fills it for 5, start fraction, 1, divided by, 4, end fraction minutes?

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

add 8+12 to get a simplified answer of 12r-20

the answer is 0.8in^2

hope you get it down chief.
