Let 
denote the cumulative distribution function for the standard normal distribution (mean 0, standard deviation 1). Then you're looking for <em>z</em> such that
(a) 
(b) 
(c) 
To get the corresponding <em>z</em>-score for each of 0.70, 0.40, and 0.25, take the inverse CDF of both sides:
(a) 
(b) 
(c) 
5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get -- 40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)
8) y intercept is (0, 15) or 15
slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)
9) y=10x+15
10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75
