A linear equation is one that has the form ax by = c. The variables x and y are variables, while the constants a, b, and c are constants. y = 4x - 3 is an example of a linear equation.

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 ...

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend.

This is a rather simplistic example. In reality, we know there are many factors that influence a person's salary. This is where multivariate linear regression comes into play. For example, suppose you ...

These coordinates represent the relationship given in the equation. For example, for y = 3x, the y value is always equal to '3 lots' of the x value. (1,3), (10,30) and (2.5,7.5) are all ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...
