Complete Question
The complete question is shown on the first uploaded image
Answer:
The line is
Step-by-step explanation:
From the question we are told that
The line is
The point is P(0,0 )
Generally the equation for a line is
Now comparing this with the given equation we see that
Generally the slope of the perpendicular to the given line is mathematically evaluated as
=>
=>
Generally from the univesal equation of a line and the given point we have that
y = mx + c at p(0,0) and is
0 = -4 (0 ) + c
=> c = 0
Hence the equation perpendicular to the line given at the point given is
