Question 981668
You have a graph, and if shown on a cartesian LABELED system, you can read some of the points.  Use the points read from the graph and write your equation.  What exactly is given to you in the exercise?  The graph, the equation, or both?  Be more exact than "the slope is weird."


Are you given just something that looks like this:
{{{graph(300,300,-5,5,-5,5,(2/3)x)}}}
?
The picture here is a graph of a line.  This line shows an infinite set of points which make the line.
You can identify the axis intercepts, and you can read ANY point on the line.  Reading integer coordinate pairs will be easiest for good accuracy.
