## Negative Slope

In the previous post we have discussed about linear equation calculator and In today’s session we are going to discuss about Negative Slope, Slope of a line is defined as a measure of steepness. Sometimes a slope is defined as the tangent of the given line that is expressed as an equation y = m x +c where m is defined the slope of the line that is equal to the m = ( y / x ) – c where c is the intercept of the line and also tan m = perpendicular / base. Slope is also defined as m = ( change in value of y ) / ( change in value of x). It can be understood by an example y = – x + 2 where value of the slope is – 1 that represents the negative slope.

Negative slope of a line is described as when a line is goes down and from left to the right side and also the negative slope of a line is defined as x coordinate of a graph is increases and the y coordinate decreases means when these definitions are written in terms of expression they are occurred as value of m < 0 that means negative value of m .(Know more about Slope in broad manner, here,)

If there are some given points of line as ( 1 , -1 ) and ( – 1 , 1 ) that are define the ( x1 , y1 ) and (x2 , y2) coordinates then calculation of a slope of line is as follows :

We have the formula of finding the slope m = y2 – y1 / x2 – x1

Here x1 = 1 , x2 = -1 , y1 = -1 and y2 = 1 , so by putting the values of x1 , x2 , y1 and y2 in the equation we get m = ( 1 ) – ( -1 ) / ( – 1 ) – ( 1 ) and by simplifying this equation them = 2 / -2 = – 1 and the slope of a given line that have the coordinate ( 1 , -1 ) and ( – 1 , 1 ) is -1.
