Question 146952: This was a two part question. I figured out the answer for A but not B.
Find components for the following vectors AB :
(a) A = (1,2) and B = (3,-7)
My answer is: from A to B [-1,4]
(b) A = (2,3) and B = (2 + 3t, 3-4t)
Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
Your answer for A is not correct.
The vector AB should be able to lead you from A to B.
Look at it this way.

for the x component and

for the y component of the vector.
You can then re-arrange those equations and determine the x and y components of the vector AB.

and

Using the values from A.

[AB]=[2,-9]
If I start at (1,2) on the grid, I need to move 2 units to the right
(positive x) and move 9 units down (negative y) to reach point (3,-7).
b) The method is the same,
For the x component,

For the y component,

[AB]=[3t,-4t]
