Generally when graphing an inequality, just plot the line, then pick the area on one side of the line.

In this case,

2x+y > -3

or

y > -2x-3

so, draw the line y=-2x-3, and pick the area above the line, where y > -2x-3

Now, as for solutions, there is no single solution here. Pick any value for x. Any value > (-2x-3) is a valid value for y.

For example, if x = -5, y>7 gives the solutions for y

If y=11, x> -7 will be the solutions for x
