Answer: y= -0.5+8
Step-by-step explanation:
Any line that is perpendicular to a line is the opposite and inverse.
Ex. for a line to be perpendicular to 2, the reverse would be -2 and the opposite is -1/2.
Now we need to focus on the b in y=mx+b.
To do that, we plug in 4 as y and -2 in x to find b.
4=2(-2)+b
4=-4+b
And we find that b is 8.
So in conclusion, y=-0.5+8
