Question 28393
find the slope of line joining (0,0)and (-6,2)

[The slope of the line joining two given points 
A(x1,y1) and B(x2,y2) is given by
m = (y2-y1)/(x2-x1)
Here in the given problem 
A(x1,y1) is the origin O(0,0) Therefore x1 = 0, y1 = 0
and B(x2,y2) is the (-6,2) Therefore x2 = -6, y2 = 2]

the slope of line  joining (0,0)and (-6,2)is
m = (2-0)/[(-6)-0]
  =2/(-6)
  =(-1/3)
