Find the slope of the line that passes through the these points (-6,-2,7,11)(23,11,-16,-28)

Graph C has a slope of -2 and goes through point (-2, 1).

In order to pick the appropriate graph in this case, we are first just looking for any graph that goes through the point (-2, 1). In order to find that, you are going to look for a line that goes through when x is at -2 and y is at 1. C is the only graph that hits at that point and is therefore the answer.
