What is the equation of the horizontal line that passes through the point (2, -3)?

see below:

Explanation:

If the line is horizontal then it is parallel to x-axis which means its slope is 0.

so you can use 'point slope formula' to get the equation.I'm using that to solve it.

point slope formula---$\frac{y - y 1}{x - x 1} = m$ (where m=slope)

so according to this ,eqn will be:
$\frac{y + 3}{x - 2} = 0$

simplifying it :

$y + 3 = 0$
therefore, $y = - 3$ (the final answer.)
