Answer:
b. -2
Step-by-step explanation:
Note the slope-intercept form: y = mx + b
Note that:
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
First, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides of the equation:
2x (-2x) + y = (-2x) + 12
y = -2x + 12
Remember, m is the variable for the term that stands for the slope (directly next to the x variable). In this case, your answer will be -2
b. -2 is your answer.

Answer:
10000
Step-by-step explanation:
Assumed that the cost price of the item is x.
It was sold at a loss of 20%:
therefore the price sold was 0.8x
If it was sold at a profit of 10%:
the price sold would have been 1.1x
Since the difference in price is 3000:
1.1x - 0.8x = 3000
0.3x = 3000
x = 10000
Answer: 33
explanation: 100/3 = 33.333, and since it isn't possible for 0.333 to be three different students being picked, there are only 33 different ways.
