This means that for every increase of $1 in the price per box, demand decreases by 1,500 boxes. Calculating the slope of a linear function Slope measures the rate of change in the dependent variable ...

They are expressed in the general form y = a + b x, where a is the y-intercept and b is the gradient. Key features of linear graphs are: gradient or slope: Represents the steepness and direction of ...

Linear functions can be depicted using a variety of representational systems, of which the three most common are equations, tables, and graphs. Students need to be able to understand information ...

Linear functions are an important concept for students to understand in math class. They can be represented using tables, graphs or equations. Teachers can use various activities to teach students how ...
