In the Standard form any Linear equation, y = ax + b, one of our exercises is to take a real world situation and plug in the numbers and solve for the root, or zero.
My question is this. Is there a general rule, or guideline for explaining which of your known numbers into it's proper place in this equation?
I know that "a" represents the change in the output, or the "y" variable
I'm a little foggy on the others...
Any help would be greatly appreciated!!
