Determine which ordered pair is a solution for the equation 2y = x - 3.
A)(3, 9)
B)(1, 5)
C)(0, -3)
D)(1, -1)

Question

Quizplus · Accepted Answer

To check if an ordered pair is a solution for an equation, we substitute the values into the equation and simplify. 
For option A: 2y = x - 3. Substituting 3 for x and 9 for y gives us 2(9) = 3 - 3, which simplifies to 18 = 0. This is not a true statement, so (3, 9) is not a solution. 
For option B: 2y = x - 3. Substituting 1 for x and 5 for y gives us 2(5) = 1 - 3, which simplifies to 10 = -2. This is not a true statement, so (1, 5) is not a solution. 
For option C: 2y = x - 3. Substituting 0 for x and -3 for y gives us 2(-3) = 0 - 3, which simplifies to -6 = -3. This is not a true statement, so (0, -3) is not a solution. 
For option D: 2y = x - 3. Substituting 1 for x and -1 for y gives us 2(-1) = 1 - 3, which simplifies to -2 = -2. This is a true statement, so (1, -1) is a solution. Therefore, the best choice is D.
