Parallel and Perpendicular Lines
Line j passes through the points (0, 0) and (c, d). Line k passes through the points (0,0) and (-d, c). Lines j and k are
perpendicular
Line m passes through the points (-4, 3) and (-4, 7). What is the slope of the line that is perpendicular to line m?
Zero
Line k has a slope of 2/3. If line m is parallel to line k, then it has a slope of
2/3
Parallel lines have the same slope.
True
