Question

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

Answer 1

Answer:

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

Answer 2

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.
