Undefined Slope. Through (97 , 73)
Mnenie [13.5K]

Answer:

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

 \frac{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

→ \frac{y-73}{x-97} = tan 90°

As, tan 90°=1/0

\frac{y-73}{x-97}=\frac{1}{0}\\

→  (x-97)×1= (y-73)×0

→ x-97 =0

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