Lines m and n given in the figure intersect each other at O. Can these lines have one more point of intersection? Why?
No, lines mand n don't have one more point of intersection because two intersecting lines have only one point of intersection.
At what point do the lines of equations 3x + 2y + 5 = 0 and 2x − 3y − 1 = 0 intersects each other? Find one more point on each of these lines. Prove that these lines are perpendicular.
