Linear Equations
... The slope or gradient of a graph can be measured looking at the increase in y that results when x increases by one unit. When given a linear function in the form y = ax + c, the slope or gradient is a. If a is positive the graph slopes upwards from left to right and if a is negative, the graph slope ...
