An art collector buys a replica of a famous sculpture. The replica has exactly the same shape as the original but is smaller. The replica is 25 cm tall, and the original sculpture is 30 cm tall. If 625 cm^3 of bronze was needed to make the replica, how much bronze was needed to make the original sculpture?

step-by-step explanation:

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
