Answer:

  • (-8, 82)
  • (3, -14)
  • (2, -12)

Explanation:

We are given the following ordered pairs in the form (x, y):

  • (-8, 82)
  • (0, 0)
  • (3, -14)
  • (2, -12)

We are being asked to determine which pairs are a solution to or, in other words, produce a true statement when plugged into the inequality:

y ≥ -9x + 6

We can test each ordered pair by plugging in its x- and y-values:

(-8, 82)

x = -8, y = 82

↓↓↓

82 ≥ -9(-8) + 6

82 ≥ 72 + 6

82 ≥ 78 ✅

So, (-8, 82) is a solution to the inequality.

(0, 0)

x = 0, y = 0

↓↓↓

0 ≥ -9(0) + 6

0 ≥ 6 ❌

So, (0, 0) is NOT a solution to the inequality.

___________________________________

(3, -14)

x = 3, y = -14

↓↓↓

-14 ≥ -9(3) + 6

-14 ≥ -27 + 6

-14 ≥ -21 ✅

So, (3, -14) is a solution to the inequality.

Remember that if a number is less negative, then it is more positive (think about a number line).

(2, -12)

x = 2, y = -12

↓↓↓

-12 ≥ -9(2) + 6

-12 ≥ -18 + 6

-12 ≥ -12 ✅

So, (2, -12) is a solution to the inequality.
