Q:

What must be true to prove that q ⊥ n? A. The slope of q must be the reciprocal of the slope of n. B. The slope of q must be the negative reciprocal of the slope of n. C. The slope of q must be the slope of n multiplied by –1. D. The slope of q must be the slope of n multiplied by –1n.

Accepted Solution

A:
Answer:BStep-by-step explanation:TO prove that q is perpendicular to n they must have a slope that's an opposite reciprocal to each other. For example the slope for q could be -5 first you must flip the equation so now its -1/5 then you change the sign to positive so now it's 1/5. Opposite meaning change sign reciprocal meaning flip the fraction.
