Question

Undefined Slope. Through (97 , 73)

Answer 1

Equation of line through (
`(x_(1),y_(1))`) having undefined slope is given by

`(y-y_(1))/(x-x_(1))=tan\alpha` where α =90°

Now ,it is given that line passes through (97, 93)

So , equation of line is

→
`(y-73)/(x-97)` = tan 90°

As, tan 90°=1/0

`(y-73)/(x-97)=(1)/(0)\\`

→ (x-97)×1= (y-73)×0

→ x-97 =0

→ x=97 , which is the required equation of line.
