Question

Write the equation of the vertical line that is drawn through the point $(2,3)$

• A. $x=3$
• B. $x=2$
• C. $y=2$
• D. $y=3$

Answer 1

The correct option is B $x=2$

As $x$ is positive and $y$ is positive, Hence the given coordinate lies in first quadrant.

Draw a vertical line through (2, 3) such that only the values of y-coordinate will change on that line. The value of x-coordinate will remain constant, and it is 2.
Hence, $x=2$

$\therefore$ The vertical line through $(2,3)$ is $x=2$.
$\therefore$ Option (b) is correct.
