Question

look at this graph: a coordinate grid with x and y axes from -10 to 10, and a horizontal line write the equation of the line.

Explanation:

Step1: Identify the line type

The line is horizontal, so its slope \( m = 0 \).

Step2: Find the y - intercept

A horizontal line has the equation \( y = b \), where \( b \) is the y - intercept. From the graph, the line passes through \( y=-7\) (since it's a horizontal line at \( y = - 7\)). So using the slope - intercept form \( y=mx + b\) with \( m = 0\) and \( b=-7\), we get \( y=0x-7=-7\).

Answer:

\( y=-7 \)
