It will be #y=-2#
You can see this from your second set of coordinates where for #x=0# you get #y=-2#:

Obviously, given the second data point #(0,-2)#
#(-2)# is a y-intercept
but the given data points (2,1), (0,-2), (-2,-3) are not points on a straight line,

The underlying equation could be a parabola (with a horizon axis of symmetry) or some more complex relationship.
Other y-intercepts are possible.
