Determine the distance between points R and S on the coordinate plane using the Pythagorean Theorem.

The distance is sqrt73 or approximately 8.54

It’s difficult to see the exact points in the picture. I’m guessing the points are: (-1, 5) and (2, -3).

I drew a dotted line from each point to visualize the triangle. How much did I move up and left to get the triangle?
I moved up 8 and left 3.
You can also find these numbers by subtracting y2-y1 and x2-x1

-3-5= -8
2-(-1)= 3

Then using the Pythagorean theorem, Plug in the values for sides a and b to find c.
