Answer:
2
Step-by-step explanation:
10-2=8.
First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4

Step-by-step explanation:
9. (2, -2) (1,0) (3,0) shade in and connect the points making it look like a 'U'
10. (-3, 1) (-4, -1) (-2,-1) not shaded and connect points making it look like ^
11. (2,-2) (1,-3) (3,-3) (0,-6) (4,-6) not shaded and connect points making it look like ^
12. (3, -1) (2,-2) (4,-2) (1,-5) (5,-5) not shaded and connect points making it look like ^
sorry for not showing the work, giving the points was the easiest way to give you the answers(:
