Question

WILL FAN AND MEDAL
Which of the following points are more than 5 units from point P(-2,-2)? Select all that apply.
A. A(1,2)
B. B(3,-1)
C. C(2,-4)
D. D(-6,-6)
E. E(-5,1)

Answer 1

Do you know the distance formula?

Answer 2

Yes (x2-x1)^2 + (y2-y1)^2

Answer 3

so apply the formula by plugging in each choice with (-2,-2)

Answer 4

let distance d=5
(x1,y1)=(-2,-2)
let the other point be (x2,y2)
find (x2,y2)by the above formula
take \[d=\pm 5\]
find two values of( x2, y2)

Answer 5

see which value matches above.

Answer 6

\[d=\sqrt{( x2-x1)^2+\left( y2-y1 \right)^2 }\]
