Question

is the graph of this equation a horizontal or vertical line? x = 5 horizontal line vertical line

Explanation:

Step1: Recall line equations

Horizontal lines have form \( y = k \) (constant \( y \)), vertical lines have form \( x = k \) (constant \( x \)).

Step2: Analyze \( x = 5 \)

The equation \( x = 5 \) has constant \( x \)-value (5) for all \( y \)-values. This matches the vertical line form.

Answer:

vertical line
