The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.
So, we can make the equation
. We need to find b, and put b in.
To find b, put in the numbers of y and x.
![10=2(-1)+b](https://tex.z-dn.net/?f=10%3D2%28-1%29%2Bb)
Solve for b:
![10=-2+b\\b=10+2\\b=12](https://tex.z-dn.net/?f=10%3D-2%2Bb%5C%5Cb%3D10%2B2%5C%5Cb%3D12)
Now replace b in the original equation with 12 and that will be the answer:
The answer is
.
