Question

give the equation for each graph.

Explanation:

Step1: Identify horizontal - line equation form

The equation of a horizontal line is $y = k$, where $k$ is the $y$ - coordinate of all points on the line.

Step2: Determine $k$ for the first graph

In the first graph, the line passes through $y=-2$, so the equation is $y = - 2$.

Step3: Identify vertical - line equation form

The equation of a vertical line is $x = h$, where $h$ is the $x$ - coordinate of all points on the line.

Step4: Determine $h$ for the second graph

In the second graph, the line passes through $x=-4$, so the equation is $x=-4$.

Answer:

The equation for the first graph is $y = - 2$.
The equation for the second graph is $x=-4$.
