Question

what is the y-intercept of the line? y=-3x

Answer 1

Y intercept is -9

Answer 2

The y intercept is when x = 0

so try plugging in 0 for x
and see what you get :)

y = -3*(0) = ?

Answer 3

hint:

y = -3x + 0
y = mx + b

b = y-intercept = 0

Answer 4

i have A.-3 B.0 C.1 D.3

Answer 5

@studio-games Hi :)
I appreciate your effort there, but it would really help if you can include an explanation with how you got to your answer ^_^

Answer 6

@austinhug
Thanks for including the options, try taking a look at the hint that @Vocaloid gave :)

Answer 7

it doesn't make seance to me

Answer 8

okay try this
the orginal equation is y=mx+b and your life is easy
b=0 because b doesnt exist in this problem

Answer 9

does that help?

Answer 10

b is the y intercept but in the equation there isnt a b

Answer 11

an example with a b would be
y=3x+2
