Question

Determine if the points are solution points to the inequalities below. If the point is a solution, enter yes. If the point is not a solution, enter no. Enter yes or no in lower case letters (no capital letters).

Answer 1

a. no

b. yes

c. yes

d. no

Explanation:

To test a solution, put the values where the variables are, and simplify to the point where you can tell whether the statement is true.

Each ordered pair is (x, y), so the first value gets substituted for x; the second value gets substituted for y.

a.

11 < 13 -2 = 11 . . . . no

b.

8 ≤ 16 -3 = 13 . . . . yes

c.

20 > 18 -4 = 14 . . . . yes

d.

9 ≥ 15 -5 = 10 . . . . no
