Question

Find the distance between these points A (5,8), B (-3, 4)

Answer 1

I don't know the distance formula off the top of my head, so I'll draw a triangle and use the pythaorean theorem. This is what the points look like when plotted. Draw a line that connects them (will be hypotenuse) and draw two legs that connect to make a triangle. After you draw the legs, find their length and input it into the pythagorean theorem.

a² + b² = c²

4² + 8² = c²

16 + 64 = c²

80 = c²

The distance (hypotenuse) is √80 or approximately 8.95, rounded to 9 units.

Hope this helps!
