Question

the line y=1/3x+2 is perpendicular to what line?

Answer 1

what is the slope of the given line ?

Answer 2

1/3

Answer 3

Correct.
Now use the face that product of slopes of perpendicular lines = -1

Answer 4

So if you required line has a slope m,
then 1/3 * m = -1

Answer 5

perpendicular slope is -3 right?

Answer 6

correct.

Answer 7

how do you find out what b is . in the equation y=mx+b

Answer 8

b can be simply any constant !
you can either assume it to be any real number , or leave it as b only.

Answer 9

Assuming that no other info is provided in the question, right ?

Answer 10

its multiple choice and give u options . but i typed out the question exactly otherwise

Answer 11

okay.
Then you'll have to choose that option where slope is provided to be -3.

Answer 12

Thank so Much, i was just confused!

Answer 13

Glad to help :)
