The equation of the horizontal line that passes through this point is $y = -2$. The equation of the vertical line that passes through this point is $x = 3$.

We are given the point $(3, -2)$. If a horizontal line passes through the given point, then each point on that line would have a y-coordinate of $-2$; therefore, the equation of the horizontal line that passes through this point is $y = -2$. If a vertical line passes through the given point, then each point on that line would have an x-coordinate of $3$; therefore, the equation of the vertical line that passes through this point is $x = 3$.
