Question

2.

Write a function rule for the table.


A. c = 18d + 11

B. c = 18d + 18

C. c = 11d + 18

D. c = 18d

Answer 1

A. c = 18d + 11

Explanation:

From the given table, we have two points : (1,29) and (2,47).

Now let us use slope formula to find the slope :

slope =18

Now we use point slope form to get the final equation.

Using point (1,29) and slope 18,

So final equation becomes c=18d +11

The answer is the Third solution.

example:

C = (18 × 2) + 11

C = 36 + 11

C = 47
