Slopes of Parallel and Perpendicular Lines

Question 1

What is the slope of line PQ?

Revolt · Accepted Answer

✔ 0; 0; undefined; The lines are perpendicular.

Question 2

What is the slope of line PQ?

Revolt · Accepted Answer

The slope of is (v – z) divided by .: (w – x); The slope of is divided by (w + a) – (x + a).: (v + b) – (z + b); Both lines have a slope that is divided by.: (v – z); Both lines have a slope that is divided by.: (w – x); Therefore, the lines are .: parallel

Question 3

(w – x)(x – w)(z – v)

Revolt · Accepted Answer

(w – x); The slope of is (v – z) divided by .: (w – x); The slope of is divided by (w + a) – (x + a).: (v + b) – (z + b); Both lines have a slope that is divided by.: (v – z); Both lines have a slope that is divided by.: (w – x); Therefore, the lines are .: parallel
