Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
Answer:
Step-by-step explanation:
(-3,-3) ; (8,-3)
![Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-3-[-3]}{8-[-3]}\\\\=\frac{-3+3}{8+3}\\\\=0](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3-%5B-3%5D%7D%7B8-%5B-3%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3%2B3%7D%7B8%2B3%7D%5C%5C%5C%5C%3D0)
Slope = 0. so, the line is parallel to x-axis
