m = (y2 -y1)/(x2 -x1)
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
_____
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1

Answer:
x-9 = 9 x-9 = -9
Step-by-step explanation:
(x - 9)^2 = 81
Take the square root of both sides
sqrt((x - 9)^2) = ±sqrt(81)
x-9 = ±9
x-9 = 9 x-9 = -9
Answer:
a. 42%
b. 16%
Step-by-step explanation:
a. According to the curve, the bottom 80% of families has about 58% of the income, so the top 20% has about 42%.
b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income. So the third quintile has about 32% − 16% = 16%.
