Answer: y=1/6x
Explanation:
1. Identify the type of graph (linear)
2. the linear line equation is y=mx+b
3. find the slope, in this case, 1/6
a. to find the slope follow the equation (y1-y2)/(x1-x2)
b. plug in the x and y of two different points ex: (0,0) and (18,3)
4. plug into the equation the slope and a set of points - 3=18(1/6) +b
5. solve for b (0)
6. plug b and the slope into the original equation
7. y=1/6x
8. Done :)
