Given information
We are given the parabola 
which is parallel to the line 
.
Step-by-step explanation
Step 1.
Required line has a form 
.
.It is normal line to the parabola
therefore use rule for slope of normal lines.
where 
represents slope of function and 
represents slope of required line.
represents slope of function and represents slope of required line.Find a slope for . That is derivative of this function.
. That is derivative of this function.
The slope of function is 
.
is .Rewrite function
as
Slope of this function is 
.
.As the required line is parallel to the line , they have equal slopes. Therefore 
.
, they have equal slopes. Therefore .Use
to find 
coordinate where required line is normal to the line of parabola.
coordinate where required line is normal to the line of parabola.
