The vertex of this parabola is at (-2,1). Which of the following could be its equation? O A. y = 4(x - 2)2 + 1 O B. * = 4(y + 1)2.2 O c. y= 4(x-2)2-1 D. x= 4(y - 1)2-2​

y intercept ( b) = 6.

Step-by-step explanation:

Given  : equation 4x + 2y=12.

To find : what is the y-intercept of the line with the equation.

Solution : We have given that 4x + 2y=12.

Equation of line  : y = mx + b

Where, m = slope , b =  y intercept.

4x + 2y=12.

Convert it into line form.

On subtracting both sides by 4x

2y = -4x + 12 .

On dividing both sides by 2.

y = -2y + 6.

On comparing m = -2 , b = 6 .

Therefore, y intercept ( b) = 6.
