Interactive GeoGebra activity: Finding the gradient of a straight line

What is the gradient of the line shown?

Interactive GeoGebra activity: Identifying equations of straight line graphs

What is the equation of the line shown?

Interactive GeoGebra activity: Straight line graphs and coordinates
Interactive GeoGebra activity: Draw the line - RECOMMENDED ACTIVITY!

Drag the blue points to match the equation given. The line will turn green if you get it correct! Click the “New line” button to have another go.
