Answer:
Equation of line through ([tex](x_{1},y_{1})[/tex]) having undefined slope is given by
[tex]\frac{y-y_{1}}{x-x_{1}}=tan\alpha[/tex] where α =90°
Now ,it is given that line passes through (97, 93)
So , equation of line is
→ [tex]\frac{y-73}{x-97}[/tex] = tan 90°
As, tan 90°=1/0
[tex]\frac{y-73}{x-97}=\frac{1}{0}\\[/tex]
→ (x-97)×1= (y-73)×0
→ x-97 =0
→ x=97 , which is the required equation of line.
