Answer:
y=(-2/3)x-9
Step-by-step explanation:
1) first put the equation in terms of y. You should get y=-(2/3)x-8.
2) parallel lines have the same slope so the slope for this line and the answer should be the same
3) using the form y=mx+b plug (-2/3) in as the slope or m
4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b
5) isolate the variable b and plug in your answer to the equation.
