Question

Which of the following equations represents a perpendicular line to 6x - 2y = 20

y = 3x + 2

y = -3x + 4

y = 1/3x-3

y= -1/3x-5

Answer 1

convert 6x-2y=20 to y=mx+b form :)

Answer 2

so y = 6x-2y?

Answer 3

y=3x+10 :)

Answer 4

so what now

Answer 5

now the opposite reciprocal of m is the slope of the new line...so the slope is -1/3
so any equation with a slope of -1/3 is perpendicular to 6x-2y=20 :)

Answer 6

so the last one :)

Answer 7

yup yup! ;)

Answer 8

k hope i helped! byee! :)
