Equations that have more than one unknown can have an infinite number of solutions. For example, \(2x + y = 10\) could be solved by: \(x = 1\) and \(y = 8\) \(x = 2 ...

A linear equation is drawn as a straight line ... 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 ...
