Answer: y=1/3x+2
Explanation:
Think about the m being the gradient, that means that you have to jump 3 places to the right to arrive to the point, and jump one going up, so the 1 jump would be on the top and the 3 on the right would be on the bottom:
1/3
Now think about the b being the intercept on the y line, so 2
