Respuesta :

1. Since the price increases as a function of the years, we can conclude it is a positive slope.

2.

[tex]\begin{gathered} (x1,y1)=(2012,15000) \\ (x2,y2)=(2015,18000) \\ m=\frac{18000-15000}{2015-2012}=\frac{3000}{3}=1000 \end{gathered}[/tex]

The slope is approximately 1000

3.

This means the price of the used cars increase by 1000 every year
