Slopes of Parallel and Perpendicular Lines

Question 6 • (A. Costello)WCA 5324 Geometry 1st Nine Weeks 26-27

Is Simon’s work correct?

Answer

No, the slope of the line 3x + 2y = –11 is not .

No, the slope of the line perpendicular to the line 3x + 2y = –11 should be .

No, he did not substitute the point and the slope into point-slope form correctly.

Yes, the work is correct.
