Slope of the line 
Step-by-step explanation:
Given that,
The point
lies on the curve
.
If
is the point lies on
.
To find:- Find the slope of line
.
So,
The coordinates of point
when it lies on 
if
then 
So,
≡
and many points can be calculated by given Equation.
Using the formula when two points
.

Then, substituting the coordinates we get,



⇒ 

Therefore,
Slope of the line
