Question

Find the distance between (-8, -1) and (0, 5). Give your answer in simplest radical form.

a. √14

b. 4√3

c. 2√3

d. 10

Answer 1

Answer:

D (10)

Step-by-step explanation:

The difference in the x-values is 8 and the difference in y-values is 6; if we draw a line for each difference and connect the points, we get a right triangle. Use pythagorean's theorem of a^2 + b^2 = c^2; 36 (6^2) + 64 (8^2) = 100 (10^2). Square root 100 to get 10
