Which is the approximate solution to the system y = 0.5x + 3.5 and y = −x + shown on the graph? (–2.7, 2.1) (–2.1, 2.7) (2.1, 2.7) (2.7, 2.1)

Judging by the question we can conclude that when we solve simultaneously we get to an answer (an x and a y). Here the second equation seems to be incomplete but we are given the choices. So our approach here is to use one equation and substitute the choices. By doing so, the answer is (–2.7, 2.1) or (–2.7, 2.15) to be exact.
