Answer:
![y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%204%5Bx%20-%201%5D%5C%3Aor%5C%3Ay%20%2B%202%20%3D%204%5Bx%20-%202%5D)
Step-by-step explanation:
First find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
Then plug each of these coordinates into the Point-Slope Formula, ![y - y_1 = m[x - x_1].](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%5Bx%20-%20x_1%5D.)
Now remember, in this formula, all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS:

Answer:
25% off
Step-by-step explanation:
$32 is 100%. 8 dollars was taken away, and since 8 is 1/4 of 32, we can divide 100% by 4 to get 25%. 25% is $8
Y = 2x + 9.74
x = number of years owned
y = total value in dollars
y = 2(0) + 9.74
y = 9.74
Substitute x with 0 because the question asks what is the value of coin when consuelo originally purchased it. So, at the time of purchase it's been 0 years since he owned it.
(a) What is the rate of change for each function? Show your work.function 1
Function 1 can be graphed and is given by the following line
y = 2x - 1
the slope of the line in this case is m = 2
Function 2
For this case you get the slope as follows
m = (y2-y1) / (x2-x1)
choosing two points and substituting
m = ((0) - (4)) / ((- 1) - (0)) = 4
(b) Which function has the greatest rate of change?
Function 2 has the greatest rate of change
m = 4
Answer:
x=-2
