Answer:
D) 3x + y = 5 and 2x -3y = 7
Step-by-step explanation:
You can plug in the x and y values into the equations, and see if they work. In this case, 3x + y = 5 and 2x -3y = 7 both satisfy (2, -1).
It's probably A because the fact that it is multiplied by 4 wouldn't change the number of zeros, and 10 to the 3rd power would be 1000 (if you include the X4 in this example it would be 4000).
