Question

Write an equation of the line that passes through the points (3,6) and (4,10) using function notation.

A.) f(x) = 4x - 6

B.) f(x) = x + 4

C.) y = x + 4

D.) y = 4x - 6

Answer 1

Given:
(3,6)
(4,10)

x = 3, 4
y = 6,10

A.) f(x) = 4x - 6
f(3) = 4(3) - 6
f(3) = 12 - 6
f(3) = 6

f(4) = 4(4) - 6
f(4) = 16 - 6
f(4) = 10

The correct choice is A.
