Question

For the graph x = 78 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences.

Answer 1

Hi!

The graph "x = 78" represents a vertical line passing through the point (78, 0).

Parallel lines always have the same slope, and for this equation a vertical line has an "undefined" slope.

Perpendicular lines have opposite inverse slopes. A line that's perpendicular to a vertical line is, of course, a horizontal line. Horizontal lines have a slope of 0.

Parallel to the equation: undefined

Perpendicular to the equation: 0
