Question

question 5
type the equation for the graph.

Explanation:

Step1: Recall line - equation form

The equation of a horizontal line is of the form $y = k$, where $k$ is a constant.

Step2: Determine the value of $k$

The line passes through the point where $y=-2$ for all $x$ - values. So $k = - 2$.

Answer:

$y=-2$
