Question

please help! i only have 4 days of school left!!!

Answer 1

Find the length of AB and the midpoint of AB. Round the length of AB to the nearest tenth if necessary.
1.A(0,-2) B(-6,-9)
2.A(8,11) B(-5,2)

Answer 2

to find length
\[\sqrt{(x-x)^2+(y-y)^2}\] do you know how to use it?

Answer 3

\[\sqrt{(0--6)^2+(-2--9)^2}\]

\[\sqrt{6^2+5^2} = \sqrt{36+25}=\sqrt{61}=7.8\]

Answer 4

to find mid point
add up the x's of the points add up the ys of the points
divide each by 2

A (0 , -2)
B (-6, -9)
------ add them
-6, -11 now divide each by 2
-- --
2 2

(-3, -5.5) mid point

Answer 5

does that make sense?
do #2 the same way

Answer 6

yes thank you so much
