Substitute values: Substitute the values of x and y into the inequality. For the point (2,1), substitute x=2 and y=1 into the inequality 2x + 15y < 20.Calculation: 2(2) + 15(1) < 20Math error check:
Perform multiplication: Perform the multiplication for each term.Calculation: 4 + 15 < 20Math error check:
Add results: Add the results of the multiplication to get the total sum on the left side of the inequality.Calculation: 4+15=19Math error check:
Compare sum: Compare the sum with the right side of the inequality to determine if the inequality holds true.Calculation: 19 < 20Math error check:
