The slopes of perpendicular line segments are 1/2 and d/3
what is the value of d?
A. d= -6
B. d= -3/2
C. d= 3/4
D. d= 6
The slopes of perpedicular lines are negative reciprocals....so
A line perpendicular to one with a slope of 1 /2 will have a slope of -2....so we have
-2 = d / 3 multiply both sides by 3
-6 = d (A)
-6
A perpendicular line can be found if you take the slope of a line and find its negative reciprical.
