- Function notation
- Table of values
- Ordered pair
- Gradient
- y-intercept
- y = mx + c
- Rule
- Cartesian plane
Task goals
- Foundation: Evaluate a linear function, including f(x) notation and negative inputs; complete a table of values; write ordered pairs; and plot and join the points.
- Proficient: Draw straight-line graphs directly from rules given in the form y = mx + c, identifying gradient and y-intercept from the rule.
- Excellence: Graph and compare two or more linear rules on the same axes, including rearranging a rule into y = mx + c form first, and interpret where lines meet.
