if you want you can use random ordered pairs to graph the line
OpenStudy (anonymous):
Nice graph!
myininaya (myininaya):
(x,-x) <- make sure they have this form

this is a line so if you get a crazy curve then you know you did something wrong
very good polpak your graph is bigger
myininaya (myininaya):
what me and polpak are showing is that this graph has a negative slope since the negative in front of the x
myininaya (myininaya):
if we had y=x
then the graph would look like

some ordered pairs on this line are
(x,-x)
(-5,5)
(-4,4)
(-1/2,1/2)
(0,0)
(1,-1)
(2,-2)
(7/3,-7/3)
(8,-8)
OpenStudy (anonymous):
what are the coordinates for the two points
OpenStudy (anonymous):
There are many points on this line.
OpenStudy (anonymous):
Pick any x. The y=-x. So plot the point (x,-x) for whatever x you pick. All the possible pairs will form a line.
