Question

is the graph of this equation a horizontal or vertical line?
y = -700
horizontal line vertical line

Explanation:

Step1: Recall line equations

Horizontal lines have the form \( y = k \) (constant \( y \), varying \( x \)). Vertical lines have \( x = k \) (constant \( x \), varying \( y \)).

Step2: Analyze \( y = -700 \)

The equation \( y = -700 \) is in the form \( y = k \), where \( k = -700 \). For all \( x \)-values, \( y \) remains \( -700 \), so it's a horizontal line.

Answer:

horizontal line
