7

9.4

2. The input-output table is accurate.

x y = 7 - 5x

-1 7 - 5(-1) = 12

0 7 - 5(0) = 7

1 7 - 5(1) = 2

2 7 - 5(2) = -3

3 7 - 5(3) = -8

A. True

b. False

3.Compare the quantity in Column A with the quantity in Column B.

Column A Column B

y-intercept of. y-intercept of

3x + y = -3 4y - 12 = 5x

a. The quantity in Column A is greater.

b.The quantity in Column B is greater.

c.The two quantities are equal.

d.The relationship cannot be determined on the basis of the information supplied.
