Question

5. Below is the graph for the equation 4x + 5y = 20. How could we changethis graph to represent the solution set for the inequality 4x + 5y < 20?Explain in detail what changes you would need to make. *

Answer 1

we have the inequality

4x+5y< 20

the solution of this inequality is the shaded area below the dashed line 4x+5y=20

To graph, the inequality, draw the dashed line 4x+5y=20 and shsded the area below this line
