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

To find the perpendicular slope of a line, just reciprocate its slope, and for finding the line parallel to it, according to purplemath.com:

"In numbers, if the one line's slope is m = 4/5, then the perpendicular line's slope will be m = –5/4. If the one line's slope is m = –2, then the perpendicular line's slope will be m =1/2. To answer this question, I'll find the slopes. Since these two lines have identical slopes, then these lines are parallel."

I hope my answer has come to your help. God bless and have a nice day ahead!
