Secondary 2 - Number and Algebra

Standard 8.NA.6 - Use algebra to graph a linear function on a coordinate graph where the y-intercept is not visible.

Included Skills:

Functions and graphs

• 6.1 Cartesian coordinates in two dimensions

• 6.2 graph of a set of ordered pairs as a representation of a relationship between two variables

• 6.3 linear functions y = ax + b

• 6.4 graphs of linear functions

• 6.5 the gradient of a linear graph as the ratio of the vertical change to the horizontal change (positive and negative gradients)

• 6.6 Play games, e.g. Battleship Game, that involve the use of 2D Cartesian coordinates to specify points.

• 6.7 Use a function machine to generate input and output values to illustrate the concept of function as "only one output for every input" and represent the function in verbal, tabular, graphical and algebraic forms.

• 6.8 Use a linear function to represent the relationship between two variables (such as distance and time when the speed is constant), show the relationship graphically and identify that the rate of change is the gradient of the graph.

• 6.9 Use a spreadsheet or graphing software to study how the graph of y = ax + b changes when either a or b varies.
