Which equation has a graph parallel to the graph of 9x+3y=-22

A y=3x-22

B y=3x+8

C y = 1/3x+12

D y=-1/3x-2

For those of you doing unit 6 lesson 6, parallel and perpendicular lines, questions 1-5

(I just did this so I know they are right)

Step-by-step explanation:

1. B

2. A

3. C

4. C

5. D

Solution:

3y = - 9x - 22

y = - 3x - 22/3

The graph parallel to this graph (9x + 3y = - 22) should have a gradient of - 3

In the choices above i. e A, B, C & D there is not a single equation with a gradient equal to - 3.
