Question

write equation relating A to B. then graph equation using the axes below

Answer 1

$A=14+B$

Explanation

Step 1

Let

A represents the amount that Amanda earns in a hour selling B books

B the number of books she sells in an hour

then,

if she earns 14 dollars per hour plus one dollar per book, the total would be

$\begin{gathered} \text{amount amanda earns}=14+\text{ (number of books she sell in an hour)} \\ \text{replace} \\ A=14+B \end{gathered}$

Step 2

graph

a) when b= 0

( it is when she sells zero books)

$\begin{gathered} \text{total =14+0} \\ A=14 \\ so,\text{ we have a coordinate}\rightarrow P1(0,14) \end{gathered}$

b) when b= 3

( it is , when she sells 3 books in an hour)

$\begin{gathered} A=14+B \\ A=14+3 \\ A=17 \end{gathered}$

therefore, when she sells 3 books in an hour, she earns 17 by that hour,so the coordinate is

$P2(3,17)$

c) using P1 and P2 draw the line

I hope this helps you
