Question

Which of the following is a solution of y < -x + 4?A.(4,4)B.(3,3)C.(-4,4) D.(1,8)

Answer 1

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!

Answer 2

do you still need the answer ??

Answer 3

yes i do

Answer 4

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.

Answer 5

And not a solution.
