Which function represents the relationship shown in the table?

Answer 1

the answer should be g(x) = 4x - (1/2)

Explanation:

Answer 2

g(x) = 4x - (1/2)

Second choice

Explanation:

Using points: (-2, -8.5) and (-1, -4.5)

y2 - y1 -4.5 - (-8.5) -4.5 + 8.5 4

slope = ----------- = --------------- = --------------- = --- = 4

x2 - x1 -1 - (-2) -1 + 2 1
