Answer
$y=3$
Work Step by Step
RECALL:
(i) Horizontal lines have a slope of 0.
(ii) Horizontal lines have equations of the form $y=k$, where k is a constant.
(iii) A horizontal line $y=k$ contains the points (x, k), where $x$ is any real number.
The given line has a slope of 0 which means that it is a horizontal line.
The line contains the point (-2, 3), which means that $k=3$.
Therefore, the equation of the line is $y=3$
