Determine Which Ordered Pairs Are Solutions To The Inequality

Determine which ordered pairs are solutions to the inequality, y < 2x - 8.?

just plug in the numbers in the equality and see which ones work

y < 2x - 8

A. (5, -10)
-10 < 2(5) - 8
-10 < 10 - 8
-10 < 2 YES

B. (3, -6)
-6 < 2(3) - 8
-6 < 6 - 8
-6 < -2 YES

C. (-4, 0)
0 < 2(-4) - 8
0 < -8 - 8
0 < -16 NO

D. (10, 5)
5 < 2(10) - 8
5 < 20 - 8
5 < 12 YES

ANSWERS: A, B, and D

Determine which ordered pairs are solutions to the inequality, y < 2x - 8.?

and
B. (3, -6)
and
D. (10, 5)

Determine which ordered pairs are solutions to the inequality?

Only the pair (-4, 0) doesn't satisfy the inequality.
If x = -4 and y = 0, 0< -16, which is not true.
The other three satisfy it.

Determine whether the ordered pair is a solution of the inequality.?

9 x + y < -8
9(-2) + (8) < -8
-18 + 8 < -8
-10 < -8

yes; it is a solution
What you do is substitute in the x and y values. An ordered pair is (x,y) so in this case x=-2 and y=8. Then just substitute them in and solve. -10 is less than -8. So (-2,8) is a solution.

Ordered Pairs & Solution to Inequality?

I need help how to figure out which ordered pair(s) is a solution to the inequality :

1. y < x - 1
[A](2,-3) [B](-1,-2) [C](4,-1) [D](0,-2)

2. 2y ≥ -2 - x
[A] (0,-3) [B](2,-2) [C](3,-1) [D](-2,-1)

3.) 3x + 5 ≥ 1y
[A](0,0) [B](-3,1) [C](-1,-1) [D](0,1)

And can you tell me how to solve it too ? Please & Thank you(: .

P.S : I hope my math teacher doesn't see this ! [:

Determine which ordered pair is a solution of 4x+ 1?

(-5, -19)

I assume you mean: 4x + 1 = y.

Well, if you plug-in "-5" for "x" and "-19" for "y" you get a true statement. If you plug in any of the other ordered pairs you do not get a true statement.
