Question

What is the midpoint of (–2, 0) and (4, –2)?

Answer 1

\[\frac{ x1 + x2 }{ 2 } \frac{ y1 + y2 }{ 2}\]

Answer 2

(-2 + 4)/2 = 1
(0 + -2)/2 = -2
So (1,-2) right?

Answer 3

(0-2)/2 = ??

Answer 4

Oh ok so (1, -1) right?

Answer 5

yup :)

Answer 6

Great job @jazy

Answer 7

Thanks @MathLegend & @hartnn (:

Answer 8

How do I find the length of one side of triangle(on a coordinate grid)?

Answer 9

I think you can use the distance formula

Answer 10

u have both endpoints , right ?

Answer 11

They don't give any measures, this is the picture and they ask for the length of line BC

Answer 12

or maybe you can find the slope of each side?

Answer 13

but I'm thinking distance formula

Answer 14

see carefully, u have both end-points !

Answer 15

and yes, distance formula it is.

Answer 16

yeah i just found the distance formula in my notes sorry!!!\[d=\sqrt{(x2 - x1) + (y2 - y1)}\]

Answer 17

And thanks again! (:

Answer 18

no problem,welcome :)
