Convert the equation into Slope Intercept form (y=mx+b).
9y = -3x + 5

slope intercept form is: (That is in the first pic)

y= - 1/3x + 5/9

slope = - 1/3

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

x/3-10=8

x/3=18

x=48
