Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw a ...

Predicting Values: Once you have a linear equation that represents a relationship, you can use it to predict values. For example, if you know the cost of producing a certain number of items, you can ...

Matching linear equations with their corresponding graphs is a fundamental skill in algebra and a crucial stepping stone for understanding more complex mathematical concepts. This exercise not only ...

Consumer surplus is the amount exceeding an equilibrium price the consumer is willing to pay. The equilibrium price is an idealized price, in which the demand for the good equals its supply. If the ...
