1.3 <strong>Rate</strong> <strong>of</strong> <strong>Change</strong>.<br />
<strong>Rate</strong> <strong>of</strong> <strong>Change</strong>:<br />
The rate at which one variable changes with<br />
another variable.<br />
As rate compares 2 variables, the change<br />
in one depends on the amount <strong>of</strong> change in the other.<br />
Dependent Variable:<br />
A variable whose value relies on the value <strong>of</strong> another<br />
Independent Variable:<br />
A variable whose values may be freely chosen<br />
When the relationship remains constant between variables<br />
is a linear relationship.<br />
The graph <strong>of</strong> a linear relationship is a straight line<br />
y –axis Independent Variable<br />
x –axis Dependent Variable<br />
Zero slope:<br />
A line with a slope <strong>of</strong> zero is horizontal.<br />
Undefined slope:<br />
A line with a slope that cannot be calculated is vertical.<br />
