Question

For which system of inequalities is (-3,1)(-3,1) a solution?

Answer 1

`H`: `{(x+y <=-2),(2x-3y <=-9):}`

Explanation:

With `x==3` and `y=1`

`color(white)("XXX")x+y=-2`
`color(white)("XXX")`So `x+y < -2` is not valid, but `x+y <= -2` is valid.

`color(white)("XXX")2x-3y =-9`
`color(white)("XXX")`So `2x-3y < 9` is not valid, but `2x-3y <= -9` is valid.

The only option for which both cases are valid is `H`
