Question

which pair of slopes could represent perpendicular lines
a. 1/7,7
b. 1/2, 2/4
c. -3/4, 4/3
d. 1/3, 1/3

Answer 1

i would say A or b

Answer 2

not b its c

Answer 3

are you sure its c? lol

Answer 4

perpendicular lines have negative reciprocal slopes. That means " flip " the slope and change the sign.
Example : if you have slope of 2/3, then negative reciprocal is -3/2 (see how I flipped the slope and changed the sign). 2/3 and -3/2 are perpendicular.

C is your answer

Answer 5

yep

Answer 6
