Answer:
I think this is the answer but I am not sure sry if I am wrong
Step-by-step explanation:
2x+y=2
y=2-2x
2x+4y=-10
2x+4×(2-2x)=-10
2x+8-8x=-10
2x-8x=-2
-6x=-2
x= 1/3
2×1/3+y=2
y=41/3
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
To find the area you need to multiply.
