determine which two equations represent perpendicular lines.?

Question

a.) y=4/7x-3
b.) y=3x-4/7
c.) y=-1/3x+4/7
d.) y=1/3x-4/7

Answer 1

2 lines are perpendicular if they have negative reciprocal slopes. That means that b and c (3 and -1/3) are perpindicular.

Answer 2

not one of the equations characterize perpindicular line, on the grounds which you are able to have one equation with an entire quantity in front of the x, and the different equation with the adverse reciprocal of the excellent quantity in front of the x.
