Question

is the graph of this equation a horizontal or vertical line?
x = -2
horizontal line vertical line

Explanation:

Step1: Recall line equations

For a vertical line, the equation is \( x = a \) (constant \( x \)-value, \( y \) can be any real number). For a horizontal line, the equation is \( y = b \) (constant \( y \)-value, \( x \) can be any real number).

Step2: Analyze \( x = -2 \)

The equation \( x = -2 \) has a constant \( x \)-value (\( x = -2 \)) and \( y \) can take any value. This matches the form of a vertical line equation.

Answer:

vertical line
