Slope Calculator

The slope calculator is designed to calculate the slope of line between two given points in the Cartesian coordinate system.

About Slope Calculator

Slope Calculator is an online geometry tool. It takes two-dimensional coordinate points (x1, y1) and (x2, y2) as an input. As a result, it gives the Slope of Line passing through those points.

What is Slope?

It's the amount of slant which the line has. Also, its value can be zero, positive, negative, or undefined. Most importantly, we need two coordinate point values to find the slope.

Slope Formula

You can easily find the slope of a line using the following formula.

m =  
y2 - y1
x2 - x1
   =  
ΔY
ΔX
   =  tan(θ)

Where,

m = Slope

(x1, y1) and (x2, y2) = Coordinate Points

tan(θ) = Angle of Incline

How to Find Slope?

Let's take an example to understand the calculation process.

Example:

Find the slope of line that passes throght the Coordinate Points (x1, y1) = (5, 10) and (x2, y2) = (8, 18).

Firstly, let's define all the values.

Here,
x1 = 5
y1 = 10
x2 = 8
y2 = 18

Now place above all values in slope formula.

m =  
y2 - y1
x2 - x1
m =  
18 - 10
8 - 5
=  
8

= 2.6667

So, we get slope(m) = 2.6667.

It's very simple to solve the equation for small numbers. But it becomes complex when we are dealing with big numbers. So, in this situation, you can use our slope calculator and make complex calculations easy and fast.

Distance Formula

Distance (d) = √(ΔX2 + ΔY2)

OR

Distance (d) = √(x2 - x1)2 + (y2 - y1)2

How to Use the Slope Calculator?
