Graphing proportional relationships from an equation
Let's graph the equation y = 2.5x. For every increase of 1 in x, y increases by 2.5. We call this the "unit rate" or "slope". The graph shows a proportional relationship because y changes at a constant rate as x changes and because y is 0 when x is 0. Created by Sal Khan.

In proportional relationships, the unit rate is the slope of the line. Changes in x lead to steady changes in y when there's a proportional relationship. We can use the unit rate to write and graph an equation of the line that represents the relationship.
