Question

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

Explanation:

Step1: Recall line equation forms

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

Step2: Analyze \( y = 5 \)

The equation \( y = 5 \) means for all \( x \)-values, \( y \) is 5. This matches the horizontal line form \( y = k \).

Answer:

horizontal line
