Question

is the graph of this equation a horizontal or vertical line? y = 80 horizontal line vertical line

Explanation:

Step1: Recall line - type rules

In the coordinate - plane, for an equation of the form $y = k$ (where $k$ is a constant), the graph is a horizontal line. For an equation of the form $x = h$ (where $h$ is a constant), the graph is a vertical line.

Step2: Analyze the given equation

The given equation is $y = 80$, where $k = 80$.

Answer:

horizontal line
