Function B has a rate of change ( or slope) of 11-5 / 3-1 = 6/2 = 3

Function L y = 6x + 4 has a rate of change of 6 . Higher than function B.

To find y intercept of function B;

y = 3x + b where b = y intercept, when x = -3 y = -7 so
-7 = 3(-3) + b giving b = 2

y intercept of Function B is 2 and of function L it is 4

L has greatest y intercept

The first carpenter is 0.4464 of the way is ahead of the second carpenter

<u>Solution:</u>

Given, Two carpenters are building a fence

After 5 minutes, one carpenter is finished 4/7 of the way

Second carpenter finished 1/8 of the way

Now, let us find the work done by each carpenter

$\begin{array}{l}{\text { For } 1^{\text {st }} \text { carpenter }=\frac{4}{7}=0.5714 \text { approximately. }} \\\\ {\text { For } 2^{\text {nd }} \text { carpenter }=\frac{1}{8}=0.125}\end{array}$

Then, extra work done by first carpenter over second carpenter = work done by first carpenter – work done by second carpenter

= 0.5714 – 0.125 = 0.4464

Hence, the 1st carpenter is 0.4464 of the way is ahead of the 2nd carpenter
