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 in two or more sentences

Answer 1

perpendicular = negative reciprocal

should multiply with -8 to give -1

-8x = -1

x = -1/-8

perpendicular slope = 1/8

(explanation: perpendicular lines have a slope that is the negative reciprocal and multiply with 8 to give -1)

parallel slope = 8

(parallel lines have the same slope)
