Question

Find the equation of the horizontal line that is drawn through the point $(0,0).$

• A. $x=0$
• B. $y=0$

Answer 1

The correct option is B $y=0$

As $x$ is zero and $y$ is zero, Hence the given point is origin.

Draw a horizontal line through (0, 0) such that only the values of $x$-coordinate will change on that line when we move left or right on that line. The value of $y$-coordinate will remain constant, and it is 0.
Hence, $y=0$

$\therefore$ The horizontal line through $(0,0)$ is $y=0$.
$\therefore$ Option (b) is correct.
