You could simply go to your course selection book (if there is one) and see if it's there. If not, then ask your guidance counselor for help or if you can automatically advance.
First you need to substitute x for -2 and y for 3 in the equation. So it would be... 6(-2) + 5 - 3(3) -12+5-9 Then your answer is -16. Hope that helped!
