Start by finding the gradient, which is m.
The concept of gradient represents the rate of change from a point to another point within a timeframe or distance. This can be solved using the rise over run formula:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the points.
Now, the equation passes through both points, so either point will have to satisfy the equation. Thus, we can put them into point-gradient form.
[tex]y - y_1 = m(x - x_1)[/tex], where [tex](x_1, y_1)[/tex] represent a point that the line passes through. You can rearrange it to yield an equation with y being the subject.
