Question 848086: The line through the points(-3,-1) and (0,5) is parallel to the line through which of the following points?
a. (1,-3) and (2,-1)
b. (1,-3) and (3,3)
c. (1,-3) and (3,-2)
d. (1,-3) and (3,-3)
Answer by swincher4391(1107)   (Show Source):
You can put this solution on YOUR website! Slope of (-3,-1) and (0,5) = (5-(-1)/(0-(-3)) = 6/3 = 2
A line that is parallel has the same slope.
(1,-3) and (2,-1) = (-1+3/2-1) = 2/1 = 2 <--- looks to be our answer, but check others.
(1,-3) and (3,3) = (3+3)/(3-1) = 6/2 = 3
(1,-3) and (3,-2) = (-2+3)/(3-1) = 1/2
(1,-3) and (3,-3) = (-3+3)/(3-1) = 0
A.
