Hello!
To find the slope, let's first distinguish two coordinates. It looks like (-2, 3) and (0, -1) are points on the line.
To find slope, we use the form y1 - y2 / x1 - x2; this means we'll divide the difference of the y-values by the difference in the x-values. Let's plug in our x- and y-values and solve.
3 - (-1) / -2 - 0
3 + 1 / -2
4 / -2
-2
The slope of the line is -2. The answer is A.
