Question

is the graph of this equation a horizontal or vertical line?
x = -50
horizontal line vertical line

Explanation:

Step1: Recall line equations

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

Step2: Analyze \( x = -50 \)

The equation \( x = -50 \) has a constant \( x \)-value (\( x = -50 \)) for all \( y \)-values. This matches the form of a vertical line.

Answer:

vertical line
