Thread: I Can't do Simple Linear Function Graphing

This is 10th grade stuff, and I can't for the life of me figure it out. It's the most basic of all graphing. Are there any good Websites that deal with algebraic graphing?

Graphing in general can be very complicated! In the most general sense it reduces to calculating and plotting a large number of points and hoping they will give you a sense of the actual graph. You entitled this "linear function graphing". You understand, do you not, that a "linear" function is so called because its graph is a straight line? And a straight line is determined by two points. So if y is a linear function of x, choose two convenient values for x, calculate the corresponding values of y, plot those two points, and draw the line between them.

HallsofIvy's explanation is great, there is also great video tutorials and interactive excercises on khanacademy.
