Question 981668: Hello, I have to write an equation of a line on a graph in either general form or slope intercept form. But they do not give you points. Usually I can look at the graph and tell what the points are in the line, but on this particular question the y intercept is 0 and the slope is weird. So how do they expect me to know what the points are to find the slope?

You can put this solution on YOUR website!
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%28300%2C300%2C-5%2C5%2C-5%2C5%2C%282%2F3%29x%29
?
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.
