In order to find the equation of a line, you need '''two things''': a) a point on the line; and b) the slope (sometimes called the gradient) of the line. But how you go about acquiring these two pieces of information, and what you do with them afterwards, can vary depending on the situation. For simplicity's sake, this article will focus on the slope-intercept equation ''y = mx + b'' instead of the point-slope form<br> ''(y - y<sub>1</sub>) = m(x - x<sub>1</sub>).'' | In order to find the equation of a line, you need '''two things''': a) a point on the line; and b) the slope (sometimes called the gradient) of the line.
