Question

Yvette is trying to calculate the distance between point C(1, 2) and point D(7, 10). Which of the following expressions will she use?

Answer 1

For the answer to the question above, this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] D = 10 I hope my answer helped you.
