It can be seen that the slope of the function depends on the position of P on the curve. The problem is to find the slope of the function at point P. A possible solution is to draw a line tangent to ...

Another effective activity is to use a graph to identify the slope of a linear function. Show students the graph of a linear function and help them identify the slope by looking at the steepness of ...

Graphing linear functions Graphing linear functions This section focuses on the key features and methods for working with linear graphs. It demonstrates how to sketch graphs from rules, derive rules ...
