You can put this solution on YOUR website! 1. No, it is not in the y = mx+b slope-intercept form for graphing.
-4y > 3 + x
y <
...
2. Solving the inequalities, set them equal to each other to solve for x.
2x+3 = -x
2x + x = -3
3x = -3
x = -1
...
Use x to solve for y and confirm.
y < 2(-1) + 3 = 1
y >= -(-1) = 1
...
Solution
(-1, 1)
