1. Systems of Inequalities

2. Investigations
Go to desmos.com and type in the equations. Copy them down onto your paper and answer the questions.

3. Definition Remember, a system just means more than one together.
System of equations- more than 1 equation (typically just 2)
System of inequalities- more than 1 inequality (as many as needed)
For a system of inequalities, the solution is what they all have in common.

4. Examples
1. y ≤ ½x x + 2y ≥ -2
y < -2x – x + 2y ≤ 2

5. Examples You try! y > 2 4. y < x x – 2y < 8 y > x+1
No solution

6. Examples- More than two equations
5. y < -3x You Try! 2x + 3y < 12
y > x > -4
x < y < 3
y > 3/4x - 1
