A(-4,-4), B(4,-2) and D(-2,2)
a) Determine AB and AD vector
My answer: AB=[8,2] and AD=[2,6]
b) A point C is determined by DC being parallel to AB and the angle ABC = 90. Calculate the coordinates of C.
I found out that C=(46/17, 54/17)
c) Another point E has the coordinates (t, 2t-1) where t = R
1) Find t so that point E is on line through C and D.
I am not able to solve this one
But I always end up with two unknown variables k and t.
The Attempt at a Solution
ED must be parallel with CD, therefore is
I don't know what to do next
