You have an ordered pair (x,y) you're given x and you have to find y, how? 
all you gotta do is substitute the x in the given linear equation and you'll find y :) I'm going to the first one to show you how.. 

The given linear equation: y=-2/7x+3 and an ordered pair (-7,y) 
substitute 7 by x:
y=-2/7(-7)+3
y=2+3
y=5 

We found y! The first ordered pair is (-7,5) 

Can you do the rest on your own? :)

how did you get the 2+3 to =5

Come on!

anonymous · Answer

is it cuz the -7+7=0 so that leaves the 2+3

No,it's actually like this:
|dw:1332100560508:dw|
