Answer:
y=-1/3x-17/3
Step-by-step explanation:
I assume you mean perpendicular to x=-3.
In that case, we would flip and take the negative. A perpendicular slope would be x=-1/3
Now we plug the point (4,-7) into the equation
y=mx+b
y=-1/3x+b
-7=-1/3*4+b
-7=-4/3+b
b= -17/3
The whole equation would be:
y=-1/3x-17/3
I hope this helps! :)
