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

5. How can you determine if the given lines are perpendicular? (1 point)
LINE #1:
point a: 3, 3
point b: 3, 0
LINE #2:
point c: 1, 3
point d: 3, 3
determine if they have slopes with opposite values
determine if they have the same slope
determine if the product of their slopes is 1
determine if the product of their slopes is –1
theyre perpendicular.
so, same goes for this: if u can answer these 2, THANK YOU.
but if u cant (which is understandable) can u tell me how to do both of these questions??? 
The answer is:
1. A = 2:3
2. C = The slopes of the two triangles are the same
3. D = No, the slopes of the new triangle would be 3:5
4. C = 41/1(2) = 3(1)/3(1)
5. D = determine if the product of their slope is 1
5/5 100% 
Mili is right.
