Plus my workings to the previous parts.
Use pythagoras to set up an equation involving d

Distance^(2) = (x2-x1)^(2) + (y2-y1)^(2)

He showed you in post 6

Do you know how to use Pythagoras to find the distance between two points?

It's just application of pythagoras

You know the distance between the two points is 2√13. This is like your hypotenuse

So (2√13)^2 = change in x-values squared plus change in y-values squared
