Q. What is the equation of the line that passes through the point (−7,−8) and has an undefined slope?Answer:
Identify Undefined Slope: An undefined slope means the line is vertical. A vertical line has an equation of the form x=a constant value. Since the line passes through the point (−7,−8), the constant value is the x-coordinate of the point, which is −7.
Equation of Vertical Line: The equation of the line is therefore x=−7. This equation represents a vertical line that passes through all points with an x-coordinate of −7, including the point (−7,−8).
