When you graph a series of (x,y) coordinates in Microsoft Excel 2010, you can use the program's built-in functions to display the equation for the line created by those data points. This allows you to ...

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 ...

Find the gradient and y-intercept for the straight line with equation \(2x + y - 13 = 0\). Rearrange the equation into the form \(y = mx + c\) using the algebraic rules for solving equations.

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 ...
