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 = 4-1/1-(-2) = 3-(-1)/3-(-1)
    5. D = determine if the product of their slope is -1
    5/5 100%
