Question

Choose the equation of the line passing through the point (1, -5) and perpendicular to y =1/5 x - 10.
a. y=5x+10
b.y=5x
c..y=-5x-10
d.y=-5x

Answer 1

@kenyababii123 a line which is perpendicular to other has -ve inverse slope
so
y=-5x+c
it passes through 1,-5
so
put x=1and y=-5
-5=-5+c
c=0
so answer is (D)
