student determined that the ordered pair left parenthesis (1,3)is a solution of the following system.
| 4 x +y=4 | |
| x +y=-2 |
His reasoning was that the ordered pair satisfies the second equation x + y=-2,since 1+(3)=2. What wentwrong?
Choose the correct answer below.
A.The ordered pair left parenthesis 1 comma negative 3 right parenthesis(1,3)is not a solution of the system because the ordered pair must be on thex-axis.
B.The ordered pair left parenthesis 1 comma negative 3 right parenthesis(1,3)is not a solution of the system because it is not a solution of the firstfirstequation.
C.The ordered pair left parenthesis 1 comma negative 3 right parenthesis(1,3)is not a solution of the system because the ordered pair must be on they-axis.
D.The ordered pair left parenthesis 1 comma negative 3 right parenthesis(1,3)is not a solution of the system because the ordered pair must be in quadrant II.
