Question

X | 1 | 2 | 3 | 4 |Y | 55.50 | 59.00 | $12.50 | $16.00 |What does It cost to create 1 craft (slope)?What is the admission fee (y-intercept)?

Answer 1

Given:

Number of crafts and total costs are given.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$$\begin{gathered} \text{Cost to create }1\text{ craft=}\frac{9-5.50}{2-1} \\ =\frac{3.50}{1} \\ =3.50 \end{gathered}$

Cost to create 1 craft is $3.50

$\begin{gathered} Admission\text{ fee=}5.50-3.50 \\ =\text{ \ 2} \end{gathered}$
