Which is the y-intercept of the function 3x - 6y = 12?

(0, - 2)

Step-by-step explanation:

The y- intercept is the point on the y- axis where the function crosses.

Let x = 0 in the equation and solve for y, that is

3(0) - 6y = 12, that is

- 6y = 12 ( divide both sides by - 6 )

y = - 2 ← y- intercept

(0, - 2 ) ← coordinates of y- intercept

if you need just tell me and i will come to the rescue.

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
