Answer:

-1/2

Step-by-step explanation:

The slope of a line is given by

m = (y2-y1)/(x2-x1)

    = (1-2)/(3-1)

    = -1/2

The slope is -1/2

Answer:

The slope is -1/2.

Step-by-step explanation:

Slope formula:

[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle \frac{1-2}{3-1}=\frac{2}{-1}=-\frac{1}{2}[/tex]

[tex]\Large\textnormal{Therefore, the slope is -1/2.}[/tex]
