Line l is perpendicular to the line with the equation \(y=\frac{-1}{5}x\) and the point(-3,10) l is on line . 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. \(y=5x-25\)
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
globaldesi to suggest if we are missing anything.
I added teh signs wrong.
