Ordered pairs :
A. (4,2)
B. (5,-2)
C.(0,-1)
D.(-3,1)
E. (2,7)
F. (8,4)
Answer:
A, B, F are solution to the inequality
Explanation:
5x - y > 4
To obtain the pairs which are solution to the linear inequality ; we plug in each orders pair of values into the inequality :
A.)
(4,2)
5x - y > 4
5(4) - 2 > 4
20 - 2 > 4
18 > 4 - - - - - - - True
B.
(5, -2)
5x - y > 4
5(5) - (-2) > 4
25 + 2 > 4
27 > 4 - - - True
C.
(0, -1)
5x - y > 4
5(0) - (-1) > 4
1 > 4 - - - - - - - Untrue
D.
(-3,1)
5x - y > 4
5(-3) - 1 > 4
-15 - 1 > 4
-16 > 4 - - - - - > Untrue
E.
(2,7)
5x - y > 4
5(2) - 7 > 4
10 - 7 > 4
3 > 4 - - - - Untrue
F.
(8,4)
5x - y > 4
5(8) - 4 > 4
40 - 4 > 4
36 > 4 - - - - - - - True
