The equation we are looking for is perpendicular to .
look at the slope 2. to make it perpendicular you must flip it and take its opposite.
2 can be written as .
flip it .
take its opposite .
the new equation is

Now you need to find be so plug the point (4,-7) into the above equation.

now plug it into the equation.
is the new equation.
