Answer:

y>x-2

Explanation:

When we see an inequality on a coordinate plane, we first treat it like a linear equation. The red inequality, or the red line, clearly has a positive slope. One can assume that this slope is 1. This line is also 2 units down, making the inequality x-2. There you have it!

Furthermore, we can tell it is the 1st choice because the line is dashed. In inequalities, the line is only dashed when the inequality contains < or >. Also, the shading is "above" the line, meaning the y must be greater than the line.
