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

-9

step-by-step explanation:

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

change of stock price/initial stock price on friday * total stock value = change of stock value
