#### Secant line equation

## How do you find the equation of the secant line?

Tthe Equation of a Secant LineFind two points on the secant line.Find the slope of the line between the two points.Plug one of your points and your slope into the point slope form of your line to obtain an equation of the line.

## What is the secant line of a function?

A secant line is a straight line joining two points on a function. (See below.) It is also equivalent to the average rate of change, or simply the slope between two points. The average rate of change of a function between two points and the slope between two points are the same thing.

## What is the meaning of secant line?

intersecting line

## What is the secant equal to?

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

## Is a secant a chord?

A secant is technically not a chord, but it contains a chord (the segment between the two red intersection points).

## What is secant line in a graph?

A secant line, also simply called a secant, is a line passing through two points of a curve. As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line.

## How do you find Secant?

The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle. The secant ratio is the reciprocal of the cosine ratio.

## What is the slope of the secant line?

A secant line has a slope equal to the average rate of change of the function between two points. It touches the graph at those two points.
