Answer:
y = -3x -4
Step-by-step explanation:
A perpendicular line has a slope that is the negative reciprocal of that of the given line. When the equation starts out in standard form, a line with negative reciprocal slope can be written by swapping the x- and y-coefficients and negating one of them.
The given x- and y-coefficients have the ratio 1:-3, so we can use the coefficients 3 and 1 for our purpose.
The usual process of making the line go through a given point can be used. That is, we can translate the line from the origin to the desired point by subtracting the point coordinates from x and y. Then we have ...
3(x+3) +(y-5) = 0

This is "an" equation. It is in no particularly recognizable form. It can be rearranged to the form y = mx + b:
3x +9 +y -5 = 0 . . . . . eliminate parentheses
y = -3x -4 . . . . . subtract terms that are not "y"

Janae is standing at a distance of 9 feet from the bottom of pole
<em><u>Solution:</u></em>
The flag pole, and the point where Janae is standing and the ground forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AB is the height of pole
AB = 12 feet
C is the point where Janae is standing
AC is the distance from the top of the pole to a point on the ground where Janae is standing
AC = 15 feet
BC is the distance between bottom of pole and the point on the ground where Janae is standing
We have to find BC
We can use pythagoras theorem for right angled triangle
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
By above definition for right angled angle triangle ABC,
Substituting the values we get,
Thus she is standing at a distance of 9 feet from the bottom of pole
