Question

Find the slope of the line that goes through the following points.
X 0, 1, 2, 3
Y -4,-3,-2,-1
A. -1
B. 1
C. -4
D. -7
Is the answer C?
I'm really confused.
Thank you

Answer 1

let's take the first pair:
(0,-4) and (1,-3) : slope = (-3-(-4))/(1-0) = 1/1 = 1
(I guess C is wrong)

second pair:
(1,-3) and (2, -2): slope = (-2+3)/2-1) = 1
mmmhhh?

third pair:
(2,-2) and (3,-1) = (-1+2)/(3-2) = 1

well, now, what do you think??
