Find an equation for the line perpendicular to y=-1/2x+4 and goes through the point (-1,10)

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.

Solve for b:

Now replace b in the original equation with 12 and that will be the

The answer is .
