Question

Determine if the ordered pair (-5, -1) is a
solution of 2x - y =-11.

Answer 1

No, when you plug is -5 for x and -1 for why, it ends up being -9 not -11. (-5,-1) is not a solution.

Answer 2

Answer:(-5,-1) is not an ordered pair

Explanation:

the ordered pair (-5,-1) is directly related to the variables (x,y) making -5=x and -1=y

so to figure out if the ordered pair is a solution you just plug in the number into their respective variable.

so the equation then becomes 2 (-5) - (-1) = -11

once you solve for the left part of the equation you are then left with -9 = -11 which we know is false.
