Question

is the graph of this equation a horizontal or vertical line? y = -7 horizontal line vertical line

Explanation:

Step1: Recall line - type rules

In the coordinate plane, the equation of a horizontal line is of the form $y = k$, where $k$ is a constant. The equation of a vertical line is of the form $x = h$, where $h$ is a constant.

Step2: Analyze the given equation

The given equation is $y=-7$, where $y$ is always equal to - 7 regardless of the value of $x$.

Answer:

horizontal line
