Answer
y=-2
Work Step by Step
Two points clearly on the line are (0,-2) and (1,-2). By going from one point to the other, we see that we move up 0 units and to the right 1 unit, giving us a rise/run slope of m= $0$.
And since the line crosses the y-axis at x=-2, b=-2, our y-intercept.
y=mx+b
y=0(x)-2
y=-2
And so our line is y=-2.
