Negative 8.

Point by Coordinates

Well, we just used the distance formula.

It's right on the x axis at x is equal to 5.

And let me just, just to make sure it's concrete for you, if this was the point 2, 3.

So you know that a is equal to x1.

If you say, OK, what combination of a and b can get me to the point let's say I want to get to the point let me go back up here.

Which is interesting.

Part d, or coordinate d, or point d.

I'll call that well, we'll call that a focus because it will be a focus.

And we see it's horizontal.

So some constant factor, some type of scaling factor, times x minus the x value of our vertex.

Construct a Point by its Coordinates

Or b which is, remember, what was b?

It's what's this y coordinate.

It puts us right over there.

This is always going to be the same as this.

5 comma 6.

Now my claim was that I can represent any point.

So we need to have a vertex right over here.

This is, I think, not too painful.

I'll transmit the coordinates for the rendezvous point

And first we're going to just look at some points that are already plotted and figure out their coordinates.

And then this coordinate up here is going to be the point b, f of b.

You remember a robot operating in a plane environment has usually 3 coordinates.

Now, suppose this is our line segment.

And what we want to do is, we want to find out the coordinates of the focal points.

Do you have everything?

Change in y, change in y, over change in x, is equal to we take the first y point, which is 3.

So let's figure out what are the coordinates of these points?
