The equation of the line that is parallel to x = 3 and goes through (4, -3) is: x = 4).
The slopes or parallel lines are always the same.
Given the equation of a vertical line, x = 3, the slope is undefined. So also, the slope of the line that is parallel to x = 3 is undefined.
If the line passes through the point (4, -3), it means it intercepts the x-axis at x = 4.
Therefore, the equation of the line that passes through (4, -3) and is parallel to x = 3 is: x = 4.
