-2

Step-by-step explanation:

pick 2 points, in this case (0,3) and (3,-3) find the change in the y and the difference in the x's using y2-y1/2, x2-x1/2, you would get -6 as the change in y and 3 as the change in x.

Slope=change in y/change in x

-6/3=-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

3x + 4y -25 =0 represents the amount of change sianna should recieve
