The answer would be 3/27. Since the probability of one equals 1/9, then three would be 3/27. If I am wrong, I am so sorry!

Answer:

  y -1 = -1(x -2)

Step-by-step explanation:

The slope of the line through the two points can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (5 -1)/(-2 -2) = 4/-4 = -1

The point-slope equation for a line through point (h, k) with slope m is ...

  y -k = m(x -h)

You have (h, k) = (2, 1) and m = -1. Putting these values into the form gives ...

  y -1 = -1(x -2)

_____

<em>Additional comment</em>

Your problem statement already has two of the three values filled in, so you only need to enter the x-coordinate of the first point: 2.

Can someone solve this and explain how you did it im struggling with it the problem is 1/2x+4=12
Elena-2011 [213]

Hello!

First: subtract 4 into 12

1/2x=8

Second: divide 8 by 1/2

x=16 because it takes 16 , 1/2 to get 8.

I hope it helps!
