To find the gradient of non-linear functions, you can use the average rate of change calculator. Note that if , then and if , then, Note that in the case of a vertical line, the horizontal displacement is zero because the line runs parallel to the y-axis. I prefer the slope-intercept form; at times, the point-slope form is helpful; some textbooks strongly prefer what they sometimes call the "intercept" form, which is often (though not always) given as being "Ax+By=C", so-called because the intercepts are at katex.render("\\small{ \\left(0,\\,\\frac{C}{B}\\right) }", typed99);(0,C/B) and katex.render("\\small{ \\left(\\frac{C}{A},\\,0\\right) }", typed98);(C/A,0).
