Answer: C
The equation (b + 4r = 7) is a missing number equation, not representing log10. The equation (p- (7q + 1/2 r) would be correct, if the 7q were a 2q. The answer to the question would have to be C, (x / y^2 √z).
Hope this helps you!

The given line is in point-slope form.
All options are also in point-slope form.
We can read the slope off the point-slope form easily.
The slope is 2.
A perpendicular to that line must have slope -1/2.
Only one line in the options has slope -1/2 and it's option B.
