Question

Use a graphing tool to solve the system. {4x−15y=−432x−3y=−2 Which ordered pair is the best estimate for the solution to the system? (5.1, 4.8) (6.5, 5.2) (5.5, 4.3) (4.8, 5.2)

Answer 1

4x−15y=−43.................y = 4x/15+43/15
2x−3y=−2..................... y = 2x/3+2/3

Using a Graphing tool, we can check that the solution is (5.5 , 4.333) which is the intersection of both lines.
