Question

is the graph of this equation a horizontal or vertical line? x = 1 horizontal line vertical line

Explanation:

Step1: Recall line - type rules

In a two - dimensional coordinate system, equations of the form $x = a$ (where $a$ is a constant) represent vertical lines. The $x$-coordinate of every point on the line is $a$, and the $y$-coordinate can take any real - value.

Step2: Analyze given equation

The given equation is $x = 1$. Here, for all values of $y$, $x$ is always equal to 1.

Answer:

vertical line
