Grace made tables of values to solve a system of equations. First, she found that the value of the solution was between 0 and 1, and then she found that It was between 0.5 and 1. Next, she made this table. X y=-4x+ 3 y-3x-1 0.5 1 0.5 0.6 0.6 0.8 0.7 0.2 1.1 0.8 -0.2 1.4 0.9 -0.6 1.7 1.0 -1 2 Which ordered pair is the best approximation of the exact solution? O A. (0.6, 0.7) O B. (0.7,0.2) O C. (0.5, 1.2) O D. (0.9, 1.0)
