Question

is the graph of this equation a horizontal or vertical line?
y = 8
horizontal line vertical line

Explanation:

Step1: Recall line equations

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

Step2: Analyze \( y = 8 \)

The equation \( y = 8 \) means for all \( x \)-values, \( y \) is always 8. This matches the form of a horizontal line.

Answer:

horizontal line
