Answer: Use points from the graph to create a table of data points. Then find a rule for the data in the table and write an equation that represents that rule. Lastly, check that the equation holds true for other data points in the table or graph.

Find two points on the line and write them out: (x1,y1) (x2,y2)
Use this formula: y2-y1/x2-x1
The answer you get is the slope which is "m" in y=mx+b
Now in y=mx+b plug in one point's y into y and x into x.
Find b
Done!
