Question

PLEASE HELP
I just need help with the last question.

1. Find me the midpoint between a and b given that A=(-1 5) and B=(7 -3)
Answer - (3,1)
2. Calculate the distance between A and B.
Answer - sqrt of 128 units
3.Find the equation in slope-intercept form of the line that is the perpendicular bisector of the segment between (-3,4) and (3,-8).
Answer- I don't know

Answer 1

What is the midpoint of (-3,4) and (3,-8)

Answer 2

umm

Answer 3

2,-2

Answer 4

nope

Answer 5

really?

Answer 6

try again

Answer 7

pay attention to the signs (negative/positive)

Answer 8

\[\left[\begin{matrix}-3+3 ,&, 4+(-8) \\ 2 & 2\end{matrix}\right]\]

Answer 9

thats its right?

Answer 10

-3+3 is 0

divide that by 2, you get 0/2 = 0

Answer 11

so the midpoint should be (0,-2)

Answer 12

woops I wasnt thinking strait I put 2

Answer 13

what next

Answer 14

now find the slope of the line through (-3,4) and (3,-8)

Answer 15

how would i do that

Answer 16

using the slope formula

m = (y2-y1)/(x2-x1)

Answer 17

-12/-1

Answer 18

is that it? or am I completely wrong again?

Answer 19

Answer 20

use this eq \[\frac{ y-y1 }{ x-x1 }=\frac{ y1-y2 }{ x1-x2 }\]
solv it you will get the desired eq..!!!
