Which is the approximate solution to the system y is equal to 0 point 5 x plus 3 point 5 and y is equal to negative 2 thirds x plus 1 third shown on the graph?

At the intersection, the two expressions for y are equal: 0.5x + 3.5 = −(2/3)x + 1/3. Solving gives x = −19/7, approximately −2.7. Substituting into y = 0.5x + 3.5 gives y ≈ 2.1, so the approximate solution is (−2.7, 2.1), choice A.
