Question

the line passing through the points (5,1 a) and (3,b,1) crosses the yz-plane at the point (0,17/2,-13/2),then what are the values of a, b?​

Answer 1

The line passing through the points (5,1,a) and (3,b,1) crosses the yz-plane at the point (0,172,-132). Then. It cuts yz-plane at (0,172,-132). This means that this point lies on the line.
