Question

In the coordinate plane shown, how far apart are points E and D? Explain how you can use the Pythagorean theorem to determine this.

Answer 1

Point E is located at (-3,5)
Point D is located at (3,-5)


using the Pythagorean theorem formula:

Distance = sqrt((x2-x1)^2 + (Yy2-y1)^2)


distance = sqrt ((3- -3)^2 + (-5,5)^2)

distance = sqrt(136)

distance = 2sqrt(34) which is approximately 11.66 units
