Question

is the graph of this equation a horizontal or vertical line?
x = 2
horizontal line vertical line
submit

Explanation:

Step1: Recall line equation types

For a line equation \( x = a \) (where \( a \) is a constant), all points on the line have the same \( x \)-coordinate (\( x = a \)) and any \( y \)-coordinate. This means the line is vertical, parallel to the \( y \)-axis. For \( y = b \) ( \( b \) constant), it's horizontal (parallel to \( x \)-axis).

Step2: Analyze \( x = 2 \)

The equation \( x = 2 \) has all points with \( x \)-coordinate 2 (and any \( y \)-value), so it's a vertical line.

Answer:

vertical line
