Homework Help: math graphs

Posted by Divergent Dauntless on Monday, May 5, 2014 at 2:05pm.

4. Which equation would you use to find out if the two lines in the graph are parallel? (1 point)

LINE #1:
point a: 1, 4
point b: -2, 1

LINE #2:
point c: 3, 3
point d: -1, -1

a. 4 - 1/-2 - 1 = 3 - 1/3 - 1
b. 4 - 1/-2 - 1 = 3 - (-1)/3 - (-1)
c. 4 - 1/1 - (-2) = 3 - (-1)/3 - (-1)
d. 1 - (-2)/4 - 1 = 3 - 1/ 3 - 1

i did my best-_-
i know, its confusing. but the graph lines are parrallel. (at least i think they are)
can someone help me? at least tell me how to do this cause my book and lesson DOES NOT.
i might post another one so.....

thanx
