y=mx%2Bb, slope-intercept form
b=y-mx, solved symbolically for b

-

y=2x%2B%282-%282%2A%28-7%29%29%29, answer in unsimplified form.

slope of given line: -1/2

slope of line perpendicular to given line: 2 (negative reciprocal of -1/2)

The equation is y+=+2x%2Bb

To find b and thus finish finding the equation of the specified line, use the fact that (x,y) = (-7,2) satisfies the equation:

2+=+2%28-7%29%2Bb

Solve for b....
