Sure, let me help you on this one!
Linear functions are written in the following format.
[tex]y=mx +b[/tex]
Let's break this up! (Helpful image attached)
Now, it should be easy for you what to place where.
As we can see on the graph, slope of this graph is 1/3, meaning that for every 3 units it goes on the run, it goes 1 unit upwards on the rise.
We can also see y-intercept coming through -4, so let's mark it as well.
Let's write the final answer!
[tex]y=1/3x-4[/tex]
