Question

is the graph of this equation a horizontal or vertical line?
x = 7
horizontal line vertical line

Explanation:

Step1: Recall line equation types

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

Step2: Analyze \( x = 7 \)

The equation \( x = 7 \) means all points on the line have \( x \)-coordinate 7, regardless of \( y \). This matches the vertical line form.

Answer:

vertical line
