Finding the Equation of Linear Graphs

Tick to show one line at a time.[br]Drag the point to see the coordinates. What do you notice?[br]In your book write an equation to describe the line.[br]Enter your equation for the line in the Input bar below. [br]See if the graph matches the line you want. [br]You can refresh the page to delete your line and continue onto the next question.

Sketching the Gradient Function

Drag the point (marked with X) to investigate the change in slope along the curve. Why does the tangent line change colour?
