What is Slope?

In literal terms, slope refers to the steepness and direction of a line. This term is used in coordinate geometry. The vector form of the slope is called gradient.

The calculation of slope involves two pairs of coordinates. Each of these pairs has two values, one is of the horizontal axis while the other is of the vertical axis.

Slope formula:

For two general points: (X1,Y1)\left(X_1,Y_1\right),(X2,Y2)\left(X_2,Y_2\right), the formula of the slope would be given as follows.

Slope = ΔyΔx\frac{\Delta \:y}{\Delta \:x}

= Change in Y / Change in X

= (Y2Y1),(X2X1)\left(Y_2-\:Y_1\right),\left(X_2-X_1\right)

This formula tells us that slope is the ratio of the difference between vertical coordinates and the difference between horizontal coordinates.

How to calculate slope?


Consider the following set of points;


Find the slope of the line passing through these points.


Step 1: Identify the values.

X1X_1 = 2

X2X_2 = 6

Y1Y_1 = 6

Y1Y_1 = 2

Step 2: Use the slope formula:

Slope = (Y2Y1),(X2X1)\left(Y_2-\:Y_1\right),\left(X_2-X_1\right)

Slope = (62),(62)\left(6-\:2\right),\left(6-2\right)

Slope = -1
