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 graph will cross the \(\text{y}\)-axis at -1.

Watch this video to learn about the equation of a straight line. Since we are given 2 points that already lie on the line, using the formula as before, we need to calculate the gradient first.
