Question

find the equation of the line shown below. your answer should take the form x = a or y = a, whichever is appropriate.

Explanation:

Step1: Identify the line type

The line is horizontal. For a horizontal line, the $y$-coordinate is constant for all $x$-values.

Step2: Determine the $y$-value

The line passes through the point where $y = - 3$. So the equation of the line is $y=-3$.

Answer:

$y = - 3$
