Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph

Solve for x math question

Colt1911 [192]

Square both sides

9(x + 2) = x + 4

Expand

9x + 18 = x + 4

Subtract x from both sides

9x + 18 - x = 4

Simplify 9x + 18 - x to 8x + 18

8x + 18 = 4

Subtract 18 from both sides

8x = 4 - 18

Simplify 4 - 18 to -14

8x = -14

Divide both sides by 8

x = -14/8

Simplify 14/8 to 7/4
