Plotting linear graphs Going from rule to graph. To sketch a linear graph from a rule, determine two points that satisfy the rule and connect them with a straight line. Two commonly used methods are: ...

b is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable. Graphing a linear function. To graph a linear function: 1. Find ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient close gradient A measure of the slope of a line. The ...

Consider the linear function: y = a + bx. b is the slope of the line. Slope means that a unit change in x, the independent variable will result in a change in y by the amount of b. slope = change in y ...
