👉 Learn about solving an inequality and graphing its solution. An inequality is a relation where the expression in the left-hand side is not equal to the expression in the right-hand side of the ...

👉 Learn how to graph piecewise functions. A piecewise function is a function that has more than one sub-function for ...

Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...
