    Line equation = \[y-y _{0}=2a(x-x _{0})\]

    y−y 0 =a(x−x 0 ) this is right

    y-9=2*(6/7)*(x-6)

    Gradient = distance up divided by distance along, i.e. gradient is \[m = \frac{y_2 - y_1}{x_2-x_1}\] Where the points have coordinates \[(x_1, y_1), (x_2, y_2)\] That is the formula you use to calculate the gradient of any line passing through two known points.

    Use \[\Large \frac{{\Delta y}}{{\Delta x}} = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}\]

    \[\Large \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{9 - 3}}{{6 - - 1}} = \frac{6}{7}\] So whoever said otherwise is incorrect.
