Bob is having a party and wants to order some cakes.   there will be 57 guests and he wants to make sure everyone gets a slice of cake.  he wants to pay as little as possible for the cakes and for them to be the same size.

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

the answer is b
