A straight line drawn on a grid can be described by a rule connecting the x and y coordinates of every point on the line. This is known as the equation of the line. The equation of any straight line ...

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 ...
