Plug in the numbers and see
4(2) - 5(4) < 20
8 - 20 < 10
-12 < 20 <==== True or False?
If True, then (2,4) IS part of the solution set.
if False, then (2,4) is NOT part of the solution set.
Since -12 is less than 20, (2,4) IS part of the solution set and the statement that (2,4) is NOT part of the solution set is FALSE
Plug in x=2 and y=4:
4(2) - 5(4) < 20
8 - 20 < 20
-16 < 20
True
