- Math - vector equation of a parallelogram -
**Reiny**, Monday, September 6, 2010 at 12:02amAre you sure your points are correct?

None of the line segments form parallel lines, (slopes are not equal)

- Math - vector equation of a parallelogram -
**Shaila**, Monday, September 6, 2010 at 12:51pmIsn't there another way to find the vector equation because they are the correct coordinates sample answers are:

[x,y]=[-1,4]+t[1,-1]

[x,y]=[-1,4]+t[2,1]

**Reiny**, Monday, September 6, 2010 at 1:51pmSure, we can find the vector equations of those lines, but I hesitated since you called it a parallelogram, which it isn't.

let's find vector equation for line BC

direction vector of BC is [4,-4] or simplified to [1,-1)

a point on there is {3,6)

equation for BC:

[x,y] = (3,6) + t(1,-1)

I still think there is something wrong with your question.
