what is the equation for the line that is perpendicular to the x-axis and passes through the point (4, -7)?
A line perpendicular to the x-axis has an infinite slope and therefore is a vertical line. Vertical lines have constant x values across the entire line. Since the line passes through the point (4,−7) , we know the constant x value is x=4
The equation of the line is: x = 4
