Provide an appropriate response.Can the point-slope form of the equation of a line be used to write an equation of a vertical line? Explain.
What will be an ideal response?
No. In the point-slope form of the equation of a line, (x - x1) is multiplied by slope, but the slope of a vertical line is undefined. (Explanations will vary.)
