anonymous · Answer

you given x=-7, and x=7 and x=7
put the x value in your equation & find y  :)

anonymous · Answer

omg this is so hard!!!

anonymous · Answer

its not... try it!
y=-2/7 *(-7) +3=2+3=...?

anonymous · Answer

sorry inik go ahead :)

anonymous · Answer

want them to do it... at least to try!

anonymous · Answer

ima try it and post my answer!

anonymous · Answer

sorry... I don't do answers only. it has to be some effort on your side....

anonymous · Answer

i  want to be able to learn how to do it myself!

anonymous · Answer

and I want to help!

-4.28

anonymous · Answer

The easiest way to do this is to plug in the x coordinates given into the equation. Then, you can get the y coordinate.

anonymous · Answer

let's try x=0:
y= -2/7  *0 +3=...?
it will give you point (0,...)

anonymous · Answer

the first one was:
y=-2/7 *(-7) +3=2+3=...?  =5 , right?
so, the first coordinate: (-7,5)
what is the second?

anonymous · Answer

(0,5)

anonymous · Answer

no...
if x=0: y= -2/7  *0 +3=3
so your coordinate: (0,3)
see it?

anonymous · Answer

let's try the last one:
x=7, so y= -2/7  *7 +3=-2+3=...
what is your last coordinate?

anonymous · Answer

yeah i think!

anonymous · Answer

(5,-7)
