How to find the slope of a secant line passing through two points. Once you have calculated the slope of a line we can find the equation of the line through the two points. When you have 2 points on a line on a graph the slope is the change in y divided by the change in x. May 14, 2025 · Calculate the secant line between two points on a function. The equation can be written in the slope-intercept form, y = m𝑥 + c (sometimes written as y = m𝑥 + b) or the point-slope form, y – y1 = m (𝑥 – 𝑥1). Jul 23, 2025 · If the secant line is passing through two points (a, f (a)) and (b, f (b)) for a function f (x), then the slope is given by the formula: m = (f (b) - f (a))/ (b - a) The calculator will find the equation of the secant line that intersects the given curve at the given points, with steps shown. This algebra video tutorial explains how to find the slope of a line given two points and from an equation. Nov 21, 2023 · A secant line is a line that passes through two or more points on the graph of a curve, while a tangent line is a line that only touches the curve at one point. Nov 7, 2023 · In cases where the secant line passes through two specific points, namely (a, f (a)) and (b, f (b)), the slope of the secant line can be determined using: Slope of the secant line = (f (b) - f (a)) / (b - a) This is also known as the "average rate of change of f (x)" from x = a to x = b. This calculus video tutorial explains how to find the equation of a secant line that intersects the curve at two points. Use our free online slope calculator to easily find the slope of a line, graph it, and learn about linear equations. veni nf kqa0 tcgm mqw sdty fb6zej tq7oi 01bkz0 ja7suc
