Question

Which of the following ordered pairs is included in the solution set of the system?

y < 3/4 x + 3 and y > 3/4 x - 1
(Points : 1)

(0, 8)


(3, 4)


(9, 1)


No Solution

Answer 1

is 3/4 x + 3 = 3x/4 +3 or 3/4x +3

Answer 2

test each point in both inequalities;
if both inequalities are true for those values, then that is the solution.
otherwise, it must not be a solution.

Answer 3

Ex) for (0,8)
8 < 3/4 (0) + 3
8 < 0 + 3
8 < 3 false!

The first inequality does not work, so it is not a solution.
