The equation will be:
y = -2
Step-by-step explanation:
A horizontal line has no slope as it is parallel to x-axis.
The horizontal line is in the form y = b where b is the y-intercept.
Given
The line passes through (4 -2).
The y-coordinate of the given point is -2 which means that the line will intersect the y-axis on -2
So,
b = -2
and
The equation will be:
y = -2
