Question

What must be true to prove that q ⊥ n?

Answer 1

Answer:

B

Step-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.
