Answer:

-x + y = 2

Explanation:

Graphing a shape means all the points in the shape will give you a true answer when you put the x and y back in the equation used to graph that shape.

Let's pick a point (0,2)

x = 1

0 = 1

This is not true, so the first option is wrong.

-x + y = 2

0 + 2 = 2

2 = 2

The second option is true.

x - y = 2

0 - 2 = 2

-2 = 2

This is not true, so the thrid option is wrong.

2x + y = 3

2(0) + 2 = 3

2 = 3

This is no true, so the fourth option is wrong.
