A type of function that can be written in the form 

, where m is the slope of the curve and b is the y-intercept. The graph of a linear function is always a straight line.

The ratio between the change in y coordinates and the change in x coordinates (rise over run). It describes the steepness of a line.

Every point in the coordinate system has coordinates of the form 

. The first coordinate tells you where the point is along the 

-axis, and the second coordinate tells you where the point is placed along the 

Change in x coordinates, also referred to as the 

Change in y coordinates, also referred to as the 

. By plotting these in a coordinate system you can visualize the relationship between the input, 

, of the function. This is what we mean by drawing a graph.
