4. (1,3); 4x - 3y = -5

5.(-1, -2); y = 3x

6. (-3, 9); y = -3x

7. (0, -1); y = 4x - 1

8.(-2, 8); y = -2x - 1

linear

step-by-step explanation:

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
