Exercise 63 Page 511

Use the Distance Formula.

sqrt(101)

Practice makes perfect

We want to find the distance between the points (0,6) and (- 1,- 4). To find this distance, we can use the Distance Formula. d=sqrt((x_2-x_1)^2+(y_2-y_1)^2) Let's substitute the given coordinates, (0,6) and (- 1,- 4), into this formula and simplify.

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

SubstitutePoints

Substitute ( 0,6) & ( - 1,- 4)

d=sqrt(( - 1- 0)^2+( - 4- 6)^2)

SubTerms

d=sqrt((- 1)^2+(- 10)^2)
