What is Slope?

Slope and gradient are two names for one thing and that is “rise over run”. In simple words, change in the y-axis divided by change in the x-axis. 


A slope gives information about the line. It tells us if the value of x is increased by “1”, by “how much” the value of y will increase. The slope is usually represented by m.  

The slope is also used to make the linear equation using Slope-intercept form.

Slope Formula

The formula of the slope is:

m = Δy/Δyyx2-x1


  • y is the position of the point on the y-axis.
  • x is the position of a point on the x-axis.

How to find Slope?


A straight line exists in the cartesian plane. The two points of the line are (2,4) and (7,5). Find the slope of line using these points. 


Step 1: Identify the points.

X1 = 2

X2 = 7

Y1 = 4

Y2 = 5

Step 2: Use the values in the formula.

m = (y2 - y1)/(x2 - x1)

m = (5 - 4)/(7 - 2)

m = 1/5

m = 0.2
