Given inequalities
- y < - x + 5
- y ≥ 1/2x - 3
- y < 4/3x + 2
Graph three lines by adding any two points belonging to the line
- For y = - x + 5, make it dashed and shade below the line,
- For y = 1/2x - 3, make it solid and shade above the line,
- For y = 4/3x + 2, make it dashed and shade below the line.
The solution is the area between the three lines, a triangle with vertices marked (see attached).
