Answer:

True

Explanation:

e Whenever you need to find the slope of a line, it is always the reciprocal with the opposite sign. For example, if your slope was 5, your slope to make it perpendicular would be -1/5. If you had the slope of -8/5, the perpendicular sope would 5/8.

Answer:

hi! so for perpendicular it's negative reciprocal!

so is -4/3 and 3/4 negative reciprocals?

oh and remember reciprocals are flipped!

if you still don't get it let me know aha
