## Slope Worksheets

Slope of a line can be defined as a gradient of line. Slope of a line represents the ratio of change in ‘Y’ to change in ‘X’ between two points on a line. If the slope of line is undefined or not defined then it is said to be a vertical line and if the slope of line is 0, then it is called as a horizontal line. Now we will talk about the equation of a line. The equation of slope of a line is given by: y = mx + c, here ‘m’ denotes the slope of a line and the y- intercept is given as ‘c’. Slope Worksheets of a line can be defined by using the following formula which are mention below:

m = a1 a2 / a1a2, herem’ is the slope of line and a1, a2 are the points on y- axis and b1, b2 are the points on x- axis. The above equation can also be described as:

=> m = a2a1 / b2 b1,

The gradient of a line can be represented by following formula:

=> m = tan θ, Now understand slope of a line with help of an example:

Suppose that a line follows two points: S = (4, 4) and T = (8, 6), therefore by the division of the change in y – coordinate by the change in x – axis, one can easily calculate the slope of the line. The formula for finding the slope of a line is:

=> m = a2a1 / b2 b1,

= 8 – 4 / 6 – 4,

= 4 / 2;

= 2; This is how we Define slope of a line. If the slope of a line is equal to -1, then two lines are perpendicular to each other. This is all about Slope Worksheets. (know more about Slope Worksheets, here)

In nature Surface Waves can be electromagnetic which is used to propagate the interface. To get more information about surface wave then see the cbse syllabus for class 9th.
