Linear equations are those equations that describe a straight line.
That is, one amount is directly proportional to another, plus a constant.
Linear Equation: y = mx + b
The secret to life, the universe and linear equations is the formula:
Note: x and y are variables while b and m are constants. The constants are
placeholders until you can fill in the value from an actual problem. They are
not variables, and once youre given a value they cannot change.
We call m the slope, because it tells you how much y increases for
each change in x. It is equal to the rise divided by the run on its graph.
We call b the y- intercept, because it tells you the value of y when x
= 0.
