Question

Write an equation for a line perpendicular to y=5x+1 and passing through the point (-5,-2)
PLease

Answer 1

can u find slope of y=5x+1 ?

Answer 2

yea 5/1

Answer 3

good, now slope of perpendicular line will be reciprocal inverse.
like if slope was m, slope of perpendicular line = -1/m
here , slope of perpendicular line will be ... ?

Answer 4

is it y=-1/5x-23??

Answer 5

+

Answer 6

-23?? (1/5x is correct)
y= -1/5 x +b

Answer 7

+23

Answer 8

y= -1/5 x +b
put x = -5, y= -2 and find b
and b does not =23

Answer 9

-1??

Answer 10

lets check.
-2 = (-5/-5) +b
-2 =1+b
b= -2-1 =... ?

Answer 11

oh nvm it -3

Answer 12

-1/5x-3

Answer 13

yes.
y= -1/5 x -3

Answer 14

omg thank u
