y stands for the value of your "y" coordinate. m stands for the way the line slopes; called the slope. x stands for the value of the "x" coordinate. b is the value of where the line crosses the yaxis. does any of that make sense?

it makes some sence... i just get confused when it comes to solving more then graphing.

as long as you can get an equation to resemble this construction (y = mx+b) then you can solve for any point on the line. Lets take your equation you gave us for an example...

I can try: In essense; we want to know what values to make "y" for any given value of "x". In your equation; we have: y + x = 7 use algebraic techniques to solve for "y"; which in this case just means subtracting (x) from both sides to get: y +xx = 7x y = x 7 ; which resembles our (y = mx + b) Do you understand it so far?

Once we have any two points that we can connect together; we can form a straight line. Many times, those two points will be where the line crosses the yaxis; and where the line crosses the xaxis. These crossing points are called "intercepts" becasue it is where the line actually gets intercepted by the x or y axis.

What two points (called coordinates) can you come up with using : y = x 7 in order to connect and make a line?
