Lesson Details
Key learning points
- Dynamic software can be used to investigate how the gradients affects the line.
- Dynamic software can be used to investigate how the intercept affects the line.
- Dynamic software can be used to investigate connections between lines, coordinates, tables and algebraic representations
Common misconception
From the line to to the lines are moving left/right rather than up/down.
It can be shown by using a coordinate in desmos. That coordinate moves up and down with the change in ''.
Keywords
Gradient - The gradient is a measure of how steep a line is.
Intercept - An intercept is the coordinate where a line or curve meets a given axis.
