THIS USER ASKED 👇
If two lines are perpendicular, which statement must be true? a. their slops are reciprocals b. their slopes are opposite c. their slopes are the same d. their slopes are negative reciprocals
THIS IS THE BEST ANSWER 👇
If there are two lines on a vertical graph, then
their slopes are negative reciprocities.
– slope of one line = 2.. . . . vertical line slope = -1/2.
– single line slope = -3/5. . . . vertical line slope = 5/3.
– slope of one line = 100.. . . vertical line slope = -0.01.
