    Put x = -3 in the equation & see if y turns out to be 4. :)

    Hey there, (-3,4) is in the form of (x,y). So 'x=-3' and 'y=4'. Simply plug these values into the equation and see if the left side equals the right side. If it does, then it is a solution.

    5(-3) -2y = -23 2y = -15 - (-23) 2y=8 y=4
