Which ordered pair is a solution of the equation 3x+y=23 (5,8) (-8,-5) (-5,-8) ( 8,5)?

you can check by plugging the points in the left side of the equation, and see whether it satisfies the value on the right side :)

It's (5,8) because if you plug in 5 where the x is and 8 where the y is it comes out to 23. 3(5)+(8)=23.
