Learn about graphing linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. i.e. linear equations have no exponents on their variables. The graph of a ...

If we are given equation of the line instead of the graph, we can still determine the gradient. Equations of straight-line graphs are given in the form: \(\text{y = 2x - 1}\) The gradient is 2 and the ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
