Question

Calculate the distance between Points A and B.
A.4.5
B.7.1
C.7.8
D.9.2

Answer 1

7.8 units separate the points A and B.

Explanation:

Going from B to A, x increases by 6 (this is the horizontal side of the triangle formed by vertices A and B), and y increases by 5. Applying the Pythagorean Theorem, we get

d = √(6² + 5²), or √(61, which is approximately 7.8, the desired distance.
