Question

is the graph of this equation a horizontal or vertical line? y = -6 horizontal line vertical line

Explanation:

Step1: Recall line - equation forms

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 $y=-6$, which is in the form $y = k$ with $k=-6$.

Answer:

horizontal line
