Question

Which of the following will always be perpendicular to −3x + y = 2?

y = 3x + c

y = one thirdx + c

y = −3x + c

y = negatve one thirdx + c

Answer 1

its the last option

Answer 2

the last one

Answer 3

Two lines will be perpendicular if their slopes are the negative reciprocals of each other.

Example: slopes are 2/3 and -3/2

So compute slopes.
