Question: A student determined that the ordered pair (1,-5) is a solution of the following system. X+Y= -4 4X+Y=3 His reasoning was that the ordered pair

A student determined that the ordered pair (1,-5) is a solution of the following system.

X+Y= -4

4X+Y=3

His reasoning was that the ordered pair satisfies the first equation X+Y= -4, Since 1+(-5)= -4.What went wrong?

1)The ordered pair (1,-5)is not a solution of the system because it is not a solution of the second equation

2)The ordered pair (1,-5)is not a solution of the system because the ordered pair must be in quadrant II.

3)The ordered pair (1,-5)is not a solution of the system because the ordered pair must be on the y-axis.

4)The ordered pair (1,-5) is not a solution of the system because the ordered pair must be on the x-axis.
