Answer:
Option 3 -
Step-by-step explanation:
Given : Perpendicular to the line ; containing the point (4,4).
To Find : An equation for the line with the given properties ?
Solution :
We know that,
When two lines are perpendicular then slope of one equation is negative reciprocal of another equation.
Slope of the equation
Converting into slope form ,
Where m is the slope.
The slope of the equation is
The slope of the perpendicular equation is
The required slope is
The required equation is
Substitute point (x,y)=(4,4)
Substitute back in equation,
Therefore, The required equation for the line is
So, Option 3 is correct.
