Question

what is the equation of the horizontal line through (-7, -3)?

Explanation:

Step1: Recall horizontal line equation

A horizontal line has the equation \( y = k \), where \( k \) is the y - coordinate of any point on the line.

Step2: Identify the y - coordinate

The point given is \((-7, - 3)\). The y - coordinate of this point is \(-3\). So, for the horizontal line passing through this point, the equation is \( y=-3 \).

Answer:

\( y = - 3 \)
