Answer 1

A. f(x) = 6.5x

B. f(x) = 3x - 2

Explanation:

Answer 2

• A. f(x) = 6.5x
• B. f(x) = 3x - 2

Explanation:

Table A

This is proportional relationship

The function is:

• f(x) = 6.5x

Table B

The slope is:

• (10 - 7)/(4 - 3) = 3

The y-intercept is:

• 10 - 4*3 = -2

The function is:

• f(x) = 3x - 2
