Answer:
D
Explanation:
Since the ordered pairs are linear then the slope m between corresponding points will be equal.
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (2, 5)
m =
=
=
Repeat with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (k, 11)
m =
=
, that is
=
( cross- multiply )
k - 6 = 8 ( add 6 to both sides )
k = 14 → D
