Answer D, "The graphs of linear functions always rise from left to right." is incorrect. If the rate of change is negative (something like y = -4x+7), the line would become more negative, or fall from left to right.

I need help with #11 and #12 how do I do this?

USPshnik [31]

Answer:

11. x = 6; y = 6.5

12. x = 2; y = 4

Step-by-step explanation:

In each figure, the hash marks on the lines indicate the parallel lines (marked with red arrows) are equally-spaced. That means the two expressions involving x are equal to each other, and the two expressions involving y are equal to each other.

11. 2x +1 = x +7

x = 6 . . . . . . . subtract (x+1) from both sides

and

3y -8 = y +5

2y = 13 . . . . add (8-y) to both sides

y = 6.5 . . . . divide by the coefficient of y

12. x +3 = 3/2x +2

1 = 1/2x . . . . . subtract (x+2)

2 = x . . . . . . . multiply by 2

and

2y -1 = 3y -5

4 = y . . . . . . add (5 -2y)
