1-8 Coordinate Plane

Distance Formula

d = the square root of (x2-x1)squared + (y2-y1)squared

Midpoint Formula

Mid = x1+x2 over 2, y1+y2 over 2.

Problem 1-8

Find the distance and midpoint

(4,3) (8,5)

d = the square root of (8-4)squared + (5-3)squared

d = the square root of 16+4

d = the square root of 20

d =

MID = 4+8 over 2, 3+5 over 2

MID = 12 over 2, 8 over 2

MID =

Distance=2 square root 5, Midpoint = (6,4)

Distance =7, Midpoint=(-3,4)

Distance=63 Midpoint = (5,20)
