Question

Find the equation of the normal to y²= 8x perpendicular to the line 2x-y-1=0

Answer 1

Dear student:

The equation of the normal to y²= 8x perpendicular to the line 2x-y-1=0

2x-y-1=0

y=2x-1

Let, $m_{1}$ is the slope of the normal

$m_{2} =2$

If normal and the given line perpendicular ot the line y=2x-1.

Then, $m_{1}m_{2} =-1$
