It would be 6x + 6y as the final expansion
So B is halfway between 0 and 1. What's half of 1? 1/2.
A is halfway between 0 and B. What's half of 1/2? 1/4.
So A is 1/4 of 1.
Alternatively -
0 - A - B - - - 1
If each - is an eighth, A is at 2/8, or 1/4

Answer:
y-1=2(x-3)
Point slope form is Y-y1=m(X-x1)
M= slope
y1= the y co-ordinate of your point
x1= the x co-ordinate of your point
The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.
According to my TI-83 calculator,
normalcdf(110,120, 100, 15) = 0.16, or 16%.
