Line l is perpendicular to the line with the equation \(y=\frac{-1}{5}x\) and the point(3,-10) is on line l . Which of the following is an equation of line l?
A. \(y=-\frac{1}{5}x-\frac{47}{5}\)
B. \(y=-\frac{1}{5}x-\frac{53}{5}\)
C. \(y=5x\)
D. \(y=5x-5\)
E. \(y=5x-25\)

B. \(y=-\frac{1}{5}x-\frac{53}{5}\)
C. \(y=5x\)
D. \(y=5x-5\)
E. \(y=5x-25\)



So none of the options satisfy the point (-3,10)

A. y = 3/5-47/5 = -44/5 != 10
B. y = 3/5-53/5 = -10 != 10
C. y = -15 != 10
D. y = -15-5 = -20 != 10
E. y = -15-25 = -40 != 10

Apologies,
I added teh signs wrong.
Corrected the signs of the point that lies on line l

aah ohk, then E seems to be the correct answer.

Another rule to keep in mind is that if two lines are perpendicular then m1m2=-1.
