Question

Find the distance between two points (-6,2) and (2,7)

Answer 1

Answer:

√89   (decimal: 9.43398...)

Step-by-step explanation:

Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2).

apply rule -(-a) = a

√(2 + 6)^2 + (7 - 2)^2

add the numbers: 2 + 6 = 8

√8^2 + (7 - 2)^2

subtract the numbers: 7 - 2 = 5

√8^2 + 5^2

8^2 = 64

√64 + 5^2

5^2 = 25

√64 + 25

add the numbers: 64 + 25 = 89

= √89
