Answer: You can simply use a calculator.
Step-by-step explanation:
If the line is perpendicular to x = 4, then that means the answer should be y = some number
and since we have the equation going through point (5,7), we look at the y-value since our equation is y=some number and replace the y-value into that equation.
So the correct answer is C. y = 7
