Question

Determine the length of the segment with endpoints P(-7,-7)and Q(9,5)Round your answer to the nearest tenth, if necessary.

Answer 1

Answer is 20 units

Step by step:

Find the difference between coordinates:

(x2-x1) = (9 - -7) = 16
(y2-y1) = (5 - -7) = 12

Square the results and sum them up:
16^2 + 12^2 = 256 + 144 = 400

Now Find the square root : √400 = 20

Your answer is 20
