please explain the concept of slope

Dear Teja,

Consider a function as :  y = f(x).

now if you find the rate of range of this particular function with respect to x:

i.e   dy/dx ; then this rate of change is known as slope.

In more simpler words consider follwing values:

at x = 3     :   y = 7

at x = 5     :   y = 10

So change in y   = 10 - 7 = 3.

and change in x  = 5 -3 = 2.

So slope can also be defined as :    change in y / change in x

                                                   =   3/2 = 1.5.

I hope now you have understood the concept of slope.
