Question

Which one of the following pairs of point co-ordinates falls on the same vertical lines

• A. Points $L(6,5)$ and $M(5,6)$
• B. Points $P(5,8)$ and $S(4,8)$
• C. Points $X(6,9)$ and $Y(9,6)$
• D. Points $T(5,7)$ and $R(5,8)$

Answer 1

The correct option is D Points $T(5,7)$ and $R(5,8)$

On a vertical line the $x-cordinate$ is always constant and $y-cordinate$ changes.

so, in above options both points $T$ and $R$ have $x=5$.

Hence (D) is correct option.
