Question

Find the distance between point A (-3, 5) and point B (5, -7) in the coordinate plane.

Answer 1

Use the distance formula
\[\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 2

ok so like (5^2 - (-3)^1) + (-7^2 - 5^1)^2?

Answer 3

\[\huge d=\sqrt{(5--3)^2+(-7-5)^2}\]
\[\huge d=\sqrt{(5+3)^2+(-7-5)^2}\]
5+3=?

Answer 4

8

Answer 5

\[\huge d=\sqrt{(8)^2+(-7-5)^2}\]
-7-5=?

Answer 6

-12

Answer 7

\[\huge d=\sqrt{(8)^2+(-12)^2}\]
8^2=?

Answer 8

64

Answer 9

\[\huge d=\sqrt{64+(-12)^2}\]
-12^2=?

Answer 10

-144

Answer 11

it would be just 144 not -144 because -12 x -12=144 (neg *neg=pos)
\[\huge d=\sqrt{64+144}\]

144+64=?

Answer 12

208

Answer 13

Good so
\[\huge~\rm~\bf~\sqrt{208}~or~14.42\]

Answer 14

Depending on what your question asks for.
