Question
Show the solution set of inequations 4x – 5y ≤ 20 graphically
✓
Answer
| Given inequality | 4x – 5y ≤ 20 |
| Corresponding equality | 4x – 5y = 20 |
| Intersection of line with X-axis | A(5, 0) |
| Intersection of line with Y-axis | B(0, – 4) |
| Origin test | 4(0) – 5(0) ≤ 20 i.e., 0 ≤ 20 which is true |
| Region | Origin side of the line |
The shaded portion represents the graphical solution.
