Slope = \frac{y_{2} -y_{1}  }{x_{2} -x_{1}  }

So taking 2 points (0,0) and (60,120)

we have slope = (120-0)/(60-0) = 120/60 = 2

general equation of linear graph is y=mx+b with m be the slope

so y=2x+b

Now to find b, just plug any point of the graph in, such as (0,0)

so we get something like 0=2(0) + b => b=0

So your equation is y=2x
