Question

just two questions i need help with

Which of the following ordered pairs is not a solution to the inequality y −4x − 2?

Answer 1

(−1, 0)

(0, 0)

(4, 4)

(1, 3)

Answer 2

Which of the following ordered pairs is a solution to the inequality y ≥4x − 2?

(0, −4)

(0, 0)

(0, −3)

(0, −5)

Answer 3

first one is actually Which of the following ordered pairs is not a solution to the inequality y ≥ −4x − 2?

Answer 4

please help anyone!

Answer 5

Check each ordered pair by substituting the values of x and y into the inequality. I'll check the first one for you.

y >= -4x - 2

(−1, 0)
0 >= -4(-1) - 2
0 >= 4 - 2
0 >= 2
Not true^

Can you do that for the rest?

Answer 6

no not really because i have no clue about inequalities

Answer 7

like the site doesnt explain it

Answer 8

wait is it -1,0

Answer 9

y >= -4x - 2 is an inequality.

Do you understand what I did here?
Substitute the ordered pairs (x, y) into the inequality.
(x, y)
(−1, 0)
y >= -4x - 2
0 >= -4(-1) - 2
0 >= 4 - 2
0 >= 2
0 is NOT greater than or equal to(>=) 2. SO (-1, 0) is wrong.

Answer 10

and is the 2nd 0,-4

Answer 11

y ≥ 4x − 2
-4 ≥ 4(0) - 2
-4 ≥ 0 - 2
-4 ≥ -2
-4 is NOT greater than/ equal to -2. So it's incorrect.
