Question

Write an equation of the line with a slope of −3 and y-intercept of 0

Answer 1

Answer:

y = -3x

Step-by-step explanation:

formula of slope is y=mx+b

you substitute the equation and you'll get

y = -3x

Answer 2

Answer:

y = -3x + 0

OR (choose one of them)

y = -3x

Step-by-step explanation:

slope intercept form: y = mx + b

slope M = -3

y-intercept  B = 0

y = -3x + 0

or

y = -3x

(When you don't put nothing after the slope the eqaution understands that the y-intercept is at the middle which is zero, so if there is nothing after the slope there is an invisible 0. So there is an invisible ( + 0) you can choose to add the + 0 or not, either way it's correct the only place where it's mandatory is if the y-intercept is NOT 0, then you write it out because the person can't guess what the y-intercept is lol.)
