Question

Find the distance between the points (1,-6) and (4,-2)

Answer 1

Heve you learned about the distance formula?

Answer 2

d=√(x2-x1)^2+(y2-y1)^2

Answer 3

that's the formula :)

Answer 4

so just plug it in
x2=4 x1=1 y2=-2 y1=1

Answer 5

are you there marcy?

Answer 6

yeah

Answer 7

\[d=√(x2-x1)^2+(y2-y1)^2\] ^Just to make the formula neater. c:

Answer 8

it's real simple keep it simple don't think to much into it. look at the formula I gave you and I broke down the points for you into x2 x1 y2 and y1

Answer 9

yeah

Answer 10

sorry i don't know how to make it neater i'm just trying to help i'll learn as i go :)

Answer 11

your fine

Answer 12

start with x2-x1 then y2-y1 keep them inside the ( )

Answer 13

The answer is 10.90 or √119 using the distance formula.

Answer 14

don't give away the answer she won't learn that way. :(

Answer 15

is it 226

Answer 16

d√(4-1)^2 + (-2-1)^2 you would get this

Answer 17

y-y1=y2-y1/x2-x1(x-x1) =4x-3y-22=0

Answer 18

good one

Answer 19

edit the board and you could finish the problem stick to one set of the parentheses at a time
