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
parallel
perpendicular
neither

Lines j and k are perpendicular.

Step-by-step explanation:

Given that Line j passes through the points (0, 0) and (c, d). Line k passes through the points (0,0) and (-d, c).

we have to find the relation between the two lines.

To find relation we have to find the slope of above to lines.

As line j passes through the points (0, 0) and (c, d)

As line k passes through the points (0,0) and (-d, c)

The slopes of above two lines i.e lines j and k are negative reciprocals therefore lines j and k are perpendicular.
