What is the slope of the line passing through the points (–3, 4) and (2, –1)?



A.




3/5


B.


–1


C.
1


D.




-5/3


Sagot :

to find the slope, we find that by (y₁-y₂)/(x₁-x₂) so
(4-(-1))/(-3-2)=5/-5 and dividing a negative by a positive=a negative so the slope is -1
the answer is B
Slope of the line using the two points (-3,4), (2,-1) given.
x1 = -3, y1 = 4,  x2 = 2, y2 =-1

m = (y2 - y1) / (x2 - x1). 

m = (-1 - 4)/(2 - - 3).

m = -5/ (2 + 3) = - 5/5.

m = -1
Therefore  slope, m = -1.
  So it is option B.
