Answer:
- 2730.54
- 18.8%
- 62.5% (decrease)
Step-by-step explanation:
The applicable formula is ...
rate = portion/base
so ...
base = portion/rate
Of course, a percentage is a fraction that has been multiplied by 100%.
__
1. base = portion/rate = 456/0.167 ≈ 2730.54
The base is about 2730.54.
__
2. rate = portion/base = 50/266 ≈ 0.18797 ≈ 18.8%
The rate is about 18.8%.
__
3. The decrease can be figured from ...
rate of change = (new amount)/(original) -1 = 33/88 -1
= -5/8 = -0.625 = -62.5%
The rate of decrease is 62.5%.

Given:
The table of values.
To find:
The slope and y-intercept for this line.
Solution:
From the given table, we have three (-4,6), (0,3), (4,0).
We need to find the slope and y-intercept for this line.
Consider any two points from the given points.
Consider the line passes through the points (0,3) and (4,0). So, the slope of the line is:
The line passes through the point (0,3). Here the x-coordinate is 0. So, the y-intercept is 3.
Therefore, the slope of the line is 
and the y-intercept of the line is 3.
