Question

Show the solution set of inequations 4x – 5y ≤ 20 graphically

Answer 1

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.
