    You need a horizontal line, so you need something like y = something. That something needs to go through the point x=-2 and y=-1. So if you had an equation y=-1, it would be horizontal and also pass through the point (-2,-1). Does that make sense?

    So how exactly do I find the answer? Is there a formula? @ybarrap

    x=-1 is a \(\bf vertical~ line\) y=-1 is a horizontal line as I indicated in the graph above: |dw:1444008098949:dw|
