How do you solve #y = -3x + 6 #, #3x-y = 6 # by graphing?
Find the intersection point in coordinate form
If you do a table of values of these two graphs and put them on the same axes, where they cross will be the solution. If they cross at (1,0) then the solution will be x=1, y=0. If they cross at (3,4), x = 3, y = 4.
In this case, I think they would cross at (2,0)
