    Let x=0 5x − 3y = 15 5(0) − 3y = 15 0-3y=15 3y=15 -- --- 3 3 y=5 (0,5)

    for starters; when x = 0 there is nothing over there and your left with -3y = 15 -3(5) does not equal 15

    just plug in your point values and see if it matches really (x=0, y=5); 5(0)-3(5)=15 0 -15 = 15 -15 = 15 is a contradiction; so the point aint part of the equation

    It's not a solution. The answer would come out as -15 instead of 15

    the solution is if there are 2 lines... the solution would be where the two lines meet
