To figure this out, you have to plug in the point and see if it equals 6
(-4,5) -4 is the x value so that replaces x, and 5 is the y value so that replaces y 2x+2y=6 2(-4)+2(5)=6 -8+10=6 2=6 ❌ this is not true, therefore A. is not the answer
(6,-3) 2x+2y=6 2(6)+2(-3)=6 12+-6=6 6=6 ✔ this is true so B. is the correct answer
