Question

Find the equation of line that is parallel of the line x=7 and contains the point (-3,2).

Answer 1

Since the coefficient of $y$ in the line $x=7$ is 0, it's a vertical line. The line that we want to find is parallel to $x=7$, so that line is vertical, too, i.e., it has the form $x=k$.

Then, as the line cointains the point $(-3,2)$, which has the x-coordinate equal to -3, our line is $\boxed{\boxed{x=-3}}$.
