HELP I NEED HELP ASAP Which function has a factor of (x+4) and a zero of -3?

A. f(x)= x^2+7x+12
B. f(x)=x^2-7x-12
C. f(x)=x^2-x+12
D. f(x)=x^2+x-12

the answers are in the images, i received 100% on this assignment. hope this !

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
