Answer:
2
Step-by-step explanation:
2x is the slope which is just 2
Answer:
X = 11
Step-by-step explanation:
So, in order to solve this equation, we need to isolate x.
So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:
-2x + 7 = -15
Now in order to get x all alone on one side, we need to subtract 7 from the left side.
-2x = -22
Now we just have to divide the -2 from x.
X = 11
