HelpmePlease: How can you tell if a graph is a linear function?
Rom is right of course
but
do you mean how do you tell if an equation will be a straight line?
It will have no squared terms
It will have no x*y terms
It will have no x or y in the denominators.
so it might look like
y=3x+4
2x+3y=7
5x/4 - 6x = 13/3
0.2y = 12- 0.8x
y=15
but it won't look like
xy=8
3/x=y
6x-x
2=4
I hope that helps.
