Answer:
<em>The slope of the line is </em>

Step-by-step explanation:
<u>The Slope of a Line
</u>
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
![\displaystyle m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
It's given the points (1,3) and (-2,2). Let's calculate the slope:
![\displaystyle m=\frac{2-3}{-2-1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7B2-3%7D%7B-2-1%7D)
Calculating:
![\displaystyle m=\frac{-1}{-3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7B-1%7D%7B-3%7D)
![\displaystyle m=\frac{1}{3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7B1%7D%7B3%7D)
The slope of the line is ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
