Kelly, her husband and two kids hosted a dinner. kelly cooked a turkey big enough to feed 20 people. only 12 people came to the dinner party. which expression shows how many days kelly and her family of 4 can eat leftover turkey dinners?
a) (20 – 12) x 4
b) (20 – 12) ÷ 4
c) (20 – 12) – 2
d) 20 – (12 x 2)

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

27 +27 or 27times 2=54

the diffrence is 0
