Learn about solving a system of equations by graphing. A system of equations is a set of more than one equation that is to be solved simultaneously. To solve a system of equations graphically, we ...

Lines which are parallel have the same gradient. For example, \(\text{y = 2x + 1}\) and \(\text{y = 2x - 2}\) will be parallel because they both have a gradient of 2. We want to determine if the lines ...

If you understand the definition of a mathematical function, a good way to judge it is that any line drawn parallel to the y-axis intersects with the values in the function’s curve only once. The same ...
