Question

Which point is 8 units from (–4, 7) on a coordinate plane?






A.

(–7, –4)






B.
(–4, –1)





C.
(–4, –7)





D.
(–4, 1)

Answer 1

7-8=?

Answer 2

-1

Answer 3

kk

Answer 4

use the formula for distance between 2 point for the 4 choices given
d = sqrt [ (y2-y1)^2 + (x2 - x1)^2]

Answer 5

eg for A it is

sqrt[(7 - -4)^2 + (-4 --7)^2]
= sqrt (11^2 + 3^2)
= sqrt 130

which is not = 8

so not A

Answer 6

Now try B
