Question

Is each line parallel, perpendicular, or neither parallel or perpendicular to a line whose slops is -3/4?

Line m, with slips 3/4
Line n, with slope 4/3
Line p, with slope -4/3
Line q, with slope -3/4

I did this on graph paper and they all seem parallel and I know they all can’t be so I’m kind of second guessing help please hahah. I need to know which one is parallel. Perpendicular. Or neither. Thank you

Answer 1

Line M is neither.

Line N is perpendicular.

Line P is neither.

Line Q is parallel.

Explanation:

Parallel lines are lines whose slope are the same. Line q is the exact same slope. It is parallel.

Perpendicular lines are lines whose slopes are the negative reciprocal of each other
`(a)/(b)`,
`-(b)/(a)`. Line n is 4/3 and is perpendicular.

Line m and p are neither.
