A 2-column table with 6 rows. The first column is labeled x with entries negative 4, negative 2, 0, 1, x, 10. The second column is labeled y with entries 14, 15, 16, 16.5, y, 21.
Which ordered pair could be the missing values represented by (x, y)?

(0, 18)
(5, 19.5)
(8, 20)
(10, 21.5)

Answer 1

Answer:

(8, 20)

Step-by-step explanation:

Function given:

• y = 16 + 0.5x

Let's try the given options:

(0, 18)

• 18 = 16+0.5*0
• 18≠ 16
• No

(5, 19.5)

• 19.5 = 16+0.5*5
• 19.5 = 16+2.5
• 19.5 ≠ 18.5
• No

(8, 20)

• 20 = 16 + 0.5*8
• 20 = 16 + 4
• 20= 20
• Yes

(10, 21,5)

• 21.5 = 16 + 0.5*10
• 21.5 = 16 + 5
• 21.5 ≠ 21
• No
