This is the equation of a horizontal line passing through the y-axis at -2

If you consider this equation in the form $y = mx+c$ , then we see that $m=0$

This means that the line has a zero slope, so it is a horizontal line.
The $y-$ intercept is $-2$

Therefore this is the equation of a horizontal line passing through the y-axis at -2.
