Exercise 56 Page 224

Use the Distance Formula.

5

Practice makes perfect

To determine the distance between two points, we use the Distance Formula. The coordinates of the given points are A(0,0) and B(4,3).

AB = sqrt((x_2-x_1)^2 + (y_2-y_1)^2)

SubstitutePoints

Substitute ( 0,0) & ( 4,3)

AB=sqrt(( 4- 0)^2+( 3- 0)^2)

Subtract terms

AB=sqrt(4^2+3^2)

Calculate power

AB=sqrt(16+9)

Add terms

AB=sqrt(25)

Calculate root

AB=5

The distance between point A and point B is 5.
