What is Slope Calculator?

The slope formula calculator has great importance in both Mathematics and Physics. It helps to find the gradient (slope) of a line by taking two points or line equations as input.

 

In addition to finding the simple slope, it finds a whole lot of other slope and line characteristics as well. These include:

 

 

What is the slope of a line?

 

Slope in math has the same meaning as in English and that is “Steepness”. Except in maths, we use the word slope for the steepness of lines and curves.

 

It is also known as gradient, incline, and slant. Daily life examples of slope include roofs, slides, and steep mountains.

 

Slope can be positive, negative, zero, or undefined. The types of slope depend on their values and the sign with the value. For a quick review, a slope that has

 

  • A positive sign then is positive
  • A negative sign then is of course negative
  • Horizontal value only means it is zero
  • Vertical value only indicates it is undefined.

 

How to find the Slope of a line?

 

If you need to find a slope quickly and without any error, you can use the slope finder for that purpose. But if you want to calculate it yourself, keep on reading the example below.

 

1. Slope Using Two Points

 

Example:

Find the slope of the line passing through points (3,6) and (8,2).

Solution:

Step 1: Identify the values.

X1 = 3

X2 = 8

Y1  = 6

Y2 = 2

Step 2: Find the difference between the points.

𝚫X = X2 - X1

= 8 - 3

= 5

𝚫Y = Y2 - Y1  

= 2 - 6

= - 4

Step 3: Solve the fraction 𝚫Y / 𝚫X.

m = 𝚫Y / 𝚫X

= -4 / 5 

= -0.8

Hence the slope of the line is -0.8 and negative in nature.

 

2. Slope using Line Equation

 

Slope can also be found if you have an equation of a line. Let’s find the slope using the line equation.

 

Example:

Find the slope of line in the following line equation.

4y – 2x + 5 = 0

Solution:

Step 1: Arrange the equation in the form of y = mx + c

4y = 2x – 5

y = (2x – 5)/4

Step 2: Simplify the right side of the equation.

y = 2x/4 – 5/4

y = 0.5x – 1.25

Now that we have the equation of the straight line, a slope can be found by comparing it to the original equation where represents the slope.

y = mx + c

y = 0.5x – 1.25

Slope (m) = 0.5

Slope formula

The slope formula is ‘rise over run’. Mathematically it can be written as:

m = (Y2 - Y1) / (X2 - X1)

m = 𝚫Y / 𝚫X

slope formula

These can be any two-point of a line in a cartesian plane.
