Answer:

(1, 22), (2, 36), (3, 50), (4, 64)

Explanation:

You can put each value of x in the equation and do the arithmetic, as in ...

y = 14(1) +8 = 22 for x = 1 ⇒ (x, y) = (1, 22)

Or you can recognize that increasing x by 1 will add 14 to the y-value:

for x = 2, y = 22 +14 = 36 ⇒ (x, y) = (2, 36)

Carrying on in this way, the sequence of y-values that corresponds to the sequence of x-values is ...

for x = 1, 2, 3, 4

y = 22, 36, 50, 64

Written as ordered pairs, these solutions are ...

(x, y) = (1, 22), (2, 36), (3, 50), (4, 64)
