Question

How do you graph `x+y>2` on the coordinate plane?

Answer 1

graph{y > -x + 2 [-10, 10, -5, 5]}

Explanation:

`x + y > 2`
`y > -x + 2`

let `x=0` for `y`-intercept.

`y = -(0) + 2`
`y = 2`

let `y=0` for `x`-intercept.

`0 = -x + 2`
`x = 2`

Plot these points on the Cartesian plane and connect the two dots with straight line. Since the y value is greater than `-x + 2` in the form `y = mx + b`, the line should be dotted and you should shade the region above the line.
