Answer: the slope is -2
Step-by-step explanation:
If you have a line that goes trough the points (x1, y1) and (x2, y2) the slope of that line is:
s = (y2 - y1)/(x2 - x1)
in this case the points are (0, 1) and (1, -1)
then the slope is:
s = (1 - (-1))/(0 - 1) = 2/-1 = -2
Then the slope is -2, the first options.
