Question

Which point is NOT a solution of (Inequality is an attachment)

Answer 1

I do not see any points. However if you look at this and find the x/y intercepts you will have:\[x+2y \le8 \rightarrow x+2(0)=8 \rightarrow x=8\] and \[x+2y=8 \rightarrow 0+2y=8 \rightarrow y=4\]
So draw a line from (0,4) through (8,0) and see if one of your points is outside the line.
