Q.(ii) The Cartesian equations of a line are x = ay + b, z = cy + d. Find its direction ratios.
2.d (ii) Ans : < a, 0, c >

Given cartesian equations of a line

We need to find the direction ratios of the line.

Consider the equation:

That is,


Now consider the next equation:

That is,


Compare both the equations (1) and (2) to get


Thus, the direction ratios of the line are
