Verify that 1.5, 5 is a solution to 2x-y=-1

Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.

2x - y = -1

2(1.5) - 5 = -1

3 - 5 = -1

-2 ≠ -1

Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!

i would say c is the best answer, hope it's right!

good luck! =)
