Distance on the Coordinate Plane

Reading Code:

Distance between the Pyret and the boot:

num-sqrt(num-sqr(line-length(9, -3)) + num-sqr(line-length(3, -2)))

An x-y coordinate plane is shown with a right triangle connecting a pyret at (-3,-2) and a boot at (9,3)

1 Where do the 9 and -3 come from?

2 Where to the 3 and -2 come from?

3 Explain how the code works.

Writing Code

An x-y coordinate plane is shown with a right triangle connecting a pyret at (0,1) and a boot at (8,7)

Now write the code to find the distance between this boot and pyret.
