Answer:
1) Slope= 2, y-intercept=4, equation: y=2x+4
2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60
Step-by-step explanation:
Slope formula: 
1. Plug in two sets of cordinates into the equation
(0,2) (2,8)
2. Solve, slope =2
3. Plug in one pair into the point slope formula
Point slope formula: 
4. y-8=2(x-2)
5.y-8=2x-4
6. y=2x+4
Do the same for the other equation
So let me give you the answer with procedure so that you can understand it better:
Let x = Number
<span>Product of 9 and Number:</span>
<span>9x </span>
<span>is 12 less than 3 times that number. So: </span>
<span>3x - 12 </span>
<span>Set them equal and solve for x like this:</span>
<span>9x = 3x - 12 </span>
<span>6x = -12 </span>
<span>x = -2
</span>I hope this is very useful for you
The statistics should the coach study is the number of points a player can get during the game. This will show how warm up before the game effective to the players in the actual game. The coach should also study the improvement of the players in each game especially those who warm up.
Since you took a red marble from the bag and didn't put it back, you now only have 14 red marbles to pick out of, and the total number of marbles i in your bag is only 51. Probability of choosing red or white is:
(14/51) + (8/51) = 22/51
