We know the slope of this line is 1/3x, which means the slope of the line that is perpendicular to it is -3x
A slope that is perpendicular to another is the negative reciprocal of the other.
The equation of a line that is perpendicular to the line y = 1/3x - 5 is y = -3x - 5
That is the simplest form.
(5)(3x)+(5)(4)+(5)(-x)
15x+20-5x
Answer: 10x+20
