Using the formula for slope, (y2-y1)/(x2-x1), we can calculate the slope between each pair of points.
Between (-1, 4) and (0, 2), we have a slope of (2-4)/(0-(-1)) = -2/1 = -2
Between (0, 2) and (1, 0), we have a slope of (0-2)/(1-0) = -2/1 = -2
Between (1, 0) and (2, -2), we have a slope of (-2-0)/(2-1) = -2/-1 = 2
Since all three slopes are the same, we can conclude that the slope of the line is -2 or option C.

Using the formula for slope, (y2-y1)/(x2-x1), we can calculate the slope between the two points.
Slope = (1-4)/(2-(-2)) = -3/4
Therefore, the answer is D. -3/4 or -3/4.
Slope = (1-4)/(2-(-2)) = -3/4
Therefore, the answer is D. -3/4 or -3/4.

Using the formula for slope, (y2-y1)/(x2-x1), we can calculate the slope between (0,0) and (3,2).
Slope = (2-0)/(3-0) = 2/3
Therefore, the answer is A. 2/3.
Slope = (2-0)/(3-0) = 2/3
Therefore, the answer is A. 2/3.

Using the formula for slope, (y2-y1)/(x2-x1), we can choose any two points from the table to calculate the slope. Let's choose (0,-4) and (3,-1).
Slope = (-1-(-4))/(3-0) = 3/3 = 1
Therefore, the answer is B. 1.
Slope = (-1-(-4))/(3-0) = 3/3 = 1
Therefore, the answer is B. 1.
