Answer
$m=\dfrac{2}{3}$
Refer to the graph below.
Work Step by Step
The slope of the line can be determined by the equation:
$m=\dfrac{y_2-y_1}{x_2-x_1}$
where $(x_1, y_1)$ and $(x_2, y_2)$ are two given points on the line.
Here, we can substitute the coordinates of the points $(-1,1)$ and $(2,3)$ to obtain:
$m=\dfrac{3-1}{2-(-1)}=\dfrac{2}{3}$
Plot the points and connect them using a line.
