Question

Find the distance between the points (-10, 5) and (-8, -3). A) 2 17 B) 8 C) 59 D) 55

Answer 1

You can use the distance formula.

The distance, d, between points (x1, y1) and (x2, y2) is


`d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`


`d = √((-8 - (-10))^2 + (-3 - 5)^2)`


`d = √(2^2 + (-8)^2)`


`d = √(4 + 64)`


`d = √(68)`


`d = 8.24...`

Answer:

B) 8

Answer 2

distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
(-10,5)....x1 = -10 and y1 = 5
(-8,-3)....x2 = -8 and y2 = -3
now sub
d = sqrt ((-8 - (-10)^2 + (-3 - 5)^2)
d = sqrt ((-8 + 10)^2 + (-8^2)
d = sqrt (2^2) + (-8^2)
d = sqrt (4 + 64)
d = sqrt 68
d = 8.25 <====
