Given points C (6,1) and D (8,5), find vector CD as an ordered pair.
It's more like you must find the change in x, change in y.
So, what is the change in x?
I have no idea how to solve this. If you know can you please explain.
Yes, I can. If you are provided with two points, say, \(\rm (x_1, y_1),(x_2 , y_2)\) then the vector will be\[\rm \langle x_2 - x_1,y_2 - y_1\rangle\]
Just like finding the slope.
Do a thing: find the slope and don't simplify it... then I'd tell you what you could do.
Yello!
4/2
Is that right?
Vector CD = < Δx, Δy >
Yes @DustinMHayes Yup @Chlorophyll That's what I told him ;)
So, if you have the slope = 4/5, then the vector will be <5,4>
If the slope is 4/2, then what will the vector be?
@DustinMHayes Where are you? Be careful with the order of coordination!
<5,4> is the answer then?
The answer is <2,4>
