Question

What is the function rule for the line

Answer 1

Answer:

The function rule is f(x) = 4x - 2.

Step-by-step explanation:

Using the points (2,6) and (0,-2) we see that the slope is

(6 - -2) / (2-0) = 8/2

= 4

Using the slope-intercept form y = m x + c    (where m = slope and c= y-intercept we see that :-

f(x) =  4x - 2
