Data Point a point on a graph showing the location of a piece of data
Line of Best Fit reflects general pattern of a graph: average of data
Linear Graph a line graph in which the data points yield a straight line
Slope the steepness of a line on a graph equal to its vertical change divided by its horizontal change
Nonlinear Graph a line graph in which the data points do not fall along a straight line
