MCQ

The pair of equations $x=1$ and $y=1$ represents

A
parallel lines
B
coincident lines
✓
intersecting lines which are perpendicular
D
intersecting lines but not perpendicular

✓

Answer

Correct option: C.

intersecting lines which are perpendicular

(c) : $x=1$ represents a line parallel to $y$-axis at a distance of 1 unit from $y$-axis and $y=1$ represents a line parallel to $x$-axis at a distance of 1 unit from $x$-axis.
$\therefore \quad$ The pair of equations intersect each other at $(1,1)$ and are perpendicular.
