Question

Which point lies in the solution set for the following system of inequalities?
x + y > 2
2x - y < 6
a: (4, 1)
b: (3, -1)
c: (0, 0)
d: (1, 3)

Answer 1

just replace the points u r given and see what happens.
for instance: if (x,y)=(3,-1) then x=3 and y=-1 then
\[ \large x+y=3+(-1)=2>2 \]
is this correct?
