The gradient of a straight line describes the slope or steepness of the line. \(\text{Gradient =}~\frac{change~in~y}{change~in~x}\) To determine the gradient of a line: choose any two points on ...
The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel ...
