Substitute the values of the first ordered pair into the inequality and see if its true. If yes it's correct. Otherwise substitute the x an y values of the second ordered pair into the inequality, repeat as necessary!
OpenStudy (sup_open~study):
do you still need the answer ??
OpenStudy (anonymous):
yes i do
OpenStudy (anonymous):
Lets test the point (1,8) in the inequality. 8 less than -1 + 4 (8 in place of y and 1 in place of x) Simplify to 8 less than 3 ? No way , not true therefore(1,8)is not in the region.

And not a solution.
