Question

Find the distance between points P(8,2) and Q(3,8) to the nearst tenth

Answer 1

7.8

Explanation:

distance formula works like this

(difference in xs)² = difference of 8 and 3 is 5² = 25

and

(difference in ys)² = difference of 2 and 8 is 6² = 36

add them = 61

square root of that = √61 = 7.8
