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.
