Answer 7

for \(5.\)

see the points

https://www.desmos.com/calculator/vb8imkbqow


the points seems to be in straight line
so choose any two ponits and form the equation of line that will be the equation of line of best fit

Answer 8

from the equation of line of best fit in the form
\(y=mx+b\), \(m\) will be the slope

we see that that as x(years) increase the value of y(dollars) decrease so , slope represents the decrease in value of the car over the years

Answer 9

so what would i put for the slope

Answer 11

consider two points
\(\large \begin{align} \color{black}{
(x_1,y_1)=(0,23)\hspace{.33em}\\~\\
(x_2,y_2)=(1,20)\hspace{.33em}\\~\\
y-y_1=m(x-x_1)\hspace{.33em}\\~\\
m=\dfrac{x_2-x_1}{y_2-y_1}\hspace{.33em}\\~\\

}\end{align}\)

Answer 12

where
\(\large\tt \begin{align} \color{black}{
\normalsize \text{m is slope }\hspace{.33em}\\~\\


}\end{align}\)
