Question

For the graph y = -8 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

Perpendicular slope: undefined

Parallel slope: zero

Explanation:

y = -8 results in a horizontal line crossing -8 on the y-axis, with a slope of zero: 0/-8. A vertical line would be perpendicular and has an undefined slope because 0 is the denominator . A line parallel to y = -8 would be any line with a slope of zero and crosses the y-axis. Parallel lines have the same slope.

Answer 2

Explanation:

The slope perpendicular to it is not defined as it goes infinitely in both sides and the slope parallel to it is 0
