Answer
$(-3, 4)$
Work Step by Step
All the points on the line $x=-3$ have an x-coordinate of $-3$.
All the points on the line $y=4$ have a y-coordinate of $4$.
The line $x=-3$ contains the point $(-3, 4)$.
The line $y=4$ also contains $(-3, 4)$.
The two lines share the common point $(-3, 4)$; therefore, their graphs will intersect at $(-3, 4)$.
