Parts of a Linear Equation

There are three major parts of a linear equation:

y and x--the variables

m--the slope-This is how much a line goes up or down divided by every unit that it goes side to side. Example: if a line goes up 2 and to the right 1, then the slope is 2. If it goes up 3 and to the right 4, then the slope is 3/4. A line that goes up and to the right has a positive slope, a line that goes down and to the right is a negative slope.

b--the y-intercept-The place where the line hits the y-axis (the vertical line)
