This study aimed to investigate eighth-grade students' difficulties and misconceptions and their performance of translation between the different representation modes related to the slope of linear ...

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 ...

Solving linear inequalities Inequalities are generally solved using the same steps as for equations, except when multiplying or dividing both sides of an inequality by a negative number, in which case ...

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 ...
