Question

Write the equation of the vertical line that is drawn through the point $(-4,-7).$

• A. $x=-4$
• B. $x=7$
• C. $y=-4$
• D. $y=7$

Answer 1

The correct option is A $x=-4$

As $x$ is negative and $y$ is negative, Hence the given coordinate lies in fourth quadrant.
Draw a vertical line through (-4, -7) such that only the values of $y$ -coordinate will change on that line. The value of $x$ -coordinate will remain constant, and it is -4.
Hence, $x=-4$

$\therefore$ The vertical line through $(-4,-7)$ is $x=-4$.
$\therefore$ Option (a) is correct.
