(8,y) and (-2,4);slope =-1/5

y = 2

Step-by-step explanation:

Calculate the slope m and equate to -

m =

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (8, y)

m = , that is

m = = -

Multiply both sides by 10 to clear the fractions

y - 4 = - 2 ( add 4 to both sides )

y = 2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
