WILL GIVE BRAINIEST ANSWER Which pair of equations would represent lines that are PERPENDICULAR to each other?
I. 3x - 2y = 12
II. 3x + 2y = -12
III. 2x - 3y = -12

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
