"The equations in the previous lab included one variable, for which you solved the equation to find its value. Now let's look at equations with multiple variables. For reasons that will become ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

Instance Variables: private int x1 - This variable represents the first x-coordinate private int x2 - This variable represents the second x-coordinate private int y1 - This variable represents the ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

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 ...
