Answer:
The slope is - 2
Step-by-step explanation:
There are two ways in which you can find the slope of this line. The way I will find is it by using the slope formula.
The slope formula
where ordered pair (X1, Y1) represents one plotted point on the line and ordered pair (X2, Y2) represents another plotted point.
Two plotted points on this line are (-1, 3) and (0, 1). Let's plug them into the formula:

The slope of the depicted line is -2
