So we get that the distance squared is equal to 1 minus negative 6.

And it really doesn't matter which x you pick to be first or second, because even if you get the negative of this value, when you square it, the negative disappears.
Be careful. The first thing we should do is identify ordered pairs to describe each position. So this side is equal to 4.
Round your answer to the nearest tenth Stuck? So let's take the square root of 170 and we get 13. If we set the starting position at the origin, we can identify each of the other points by counting units east right and north up on the grid.
We're just sitting on the x-axis. This distance is the distance squared. The larger y is here. This is the same distance as that distance right there.
The Distance Formula. I don't want to confuse you. What is the radius of this circle? But let's apply it to a couple more, and I'll just pick some points at random. To find the length c , take the square root of both sides of the Pythagorean Theorem. So we could write the distance squared is equal to-- what's our change in x?
You see that the distance is equal to x2 minus x1 minus x1 squared plus y2 minus y1 squared. Distance Formula and Pythagorean Theorem The distance formula is derived from the Pythagorean theorem. I'm just taking the larger y-value minus the smaller y-value, the larger x-value minus the smaller x-value. Figure 14.
So plus 11 squared is equal to d squared.
