You can put this solution on YOUR website! how do i put the graph here if i cant!! well i will try well on second thoughts i cant put a graph of it but you just put it in slope intercept like this
y=mx+b
m is the slope
x is the x you are going to use
b is the y-intercept
so first you plot 4 on the y intercept line then you count 2 squares up and run 1 square then you go like that until the graph finishes :)
