its not D.

hartnn · Answer

you need only 2 points,
take any 2 of these 4 points and apply the formula

hartnn · Answer

The slope of the line through points (x1,y1) and (x2,y2) is given by :
$\huge m=\frac{y_1-y_2}{x_1-x_2}$
now,just put the values and find m.

hartnn · Answer

did u get slope as 1 ?

anonymous · Answer

I got -1, i probably did somthing wrong, i suckk at math

hartnn · Answer

lets take 2 points as 0,0 and 1,1 :)

hartnn · Answer

y1 - y2 = numerator = 1-0 = 1

x1-x2 = denominator = 1-0 = 1 

so, m = 1/1 = 1 :)
