First you'll need to isolate the equations so that y is on one side.
y is already on the left side in the second equation, so let's do the same for the first equation.
x+3y > -3
1. Subtract x from both sides.
3y > -3-x
2. Divide both sides by 3.
y > -1-1/3x
Now you have two equations that you can graph.
- y > -1-1/3x
- y < 1/2x + 1
I'll try to explain how to graph them, but I'll also attach a graph.
y > -1-1/3x
- Go to -1 on the y axis and go down 1, over 3 units. The line will be a dotted line because > is not equal to as well. Since it is greater than, >, you will shade above the line you make.
y < 1/2x + 1
- Go to 1 on the y axis and go up 1, over 2 units. The line is also dotted because < is not equal to (≤). Since it is less than, <, you will shade below the line you make.
Answer is:
Here is the final graph.
The red line is y > -1-1/3x, the blue line is y < 1/2x + 1.
