Question

Find the distance between the points (-3, 3) and (3, -3). If necessary, round your answer to two decimal places.

Answer 1

the distance between the points (x1,y1) and (x2,y2) is
D=
`√((x2-x1)^2+(y2-y1)^2)`

given
(-3,3) and (3,-3)
D=
`√((3-(-3))^2+(-3-3)^2)`
D=
`√((3+3)^2+(-6)^2)`
D=
`√((6)^2+36)`
D=
`√(36+36)`
D=√72
D=(√36)(√2)
D=6√2

the disatnce is 6√2
about 8.48

answer is A
