No, ur friend is not correct
| 3x + 8 | - 9 = -5....u have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides
| 3x + 8 } = -5 + 9
| 3x + 8 | = 4...so that number is not negative anymore
now u can set up ur 2 equations and solve for x...ur 2 equations would be:
3x + 8 = 4 and 3x + 8 = -4...so there will be 2 solutions
** if that -9 would not have been there, then ur friend would have been correct
First we need to isolate the y in the equation
-4y=16-2x (subtract the 2x)
4y=2x-16 (divide both sides by -1)
y=1/2x-4 (divide both sides by 4)
The we know the slope of this line is 1/2. I'm not sure what the choices are, but the answer would have to have a slope of 1/2. For example, y=1/2x+2 might be an answer.
Hope this helps
