Linear equations are written in the form $$y = mx + c$$ where $$y$$ is the dependent variable; $$m$$ is the gradient/slope; $$x$$ is the independent variable and $$c$$ is the $$y$$-intercept.

The biggest power of the independent variable, $$x$$ is 1, which implies that all linear equations are of order 1. These equations can be represented graphically with a straight line, hence the name linear equation. https://mathsgee.com/qna/31484/what-is-a-linear-equation
