PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.
Answer:
Answer is on the pic
Step-by-step explanation:
I hope it's helpful!
Number Line A, well the first number line.
The open circle shows us that -5 is NOT in the solution. All the numbers greater than -5 ( x > -5) are in the solution.

Simple random selection involves a selection where all the elements in the dataset have the same chance of being selected.
The selected names are:
<em>Engler, Motola, Redmond and Zenkel</em>
We have:
--- All names
---- Sample to select
There are several ways to select a sample of 4 using a simple random sample. Some ways are:
- <em>Select any 4</em>
- <em>List all names in even position and select the first 4</em>
- <em>List all names in position divide by 4 and select any 4 that is divided by 8</em>
- <em>List all names in odd position and select the first 4 that can be divided by 3</em>
- <em>Etc</em>
<em />
Going by the third method, the selected positions are:
4, 8, 12, 16, 20, 24, 28 and 32
Select 4 positions that can be divided by 8
8, 16, 24 and 32
So, the selected names are:
<em>Engler, Motola, Redmond and Zenkel</em>

Answer:
option A
Step-by-step explanation:
Notice that you need to emulate the series: 1 + 5 + 25 + 125 + 625 (a five total term series)
with the indicated sums.
The first term in the your series (addition) has to be "1". This fact already gets rid of two of the suggested sums (B, and D) because their first term is
.
So, now analyzing the options A and C, we notice that A has a sum from i=0 to 4 (which gives a total of five terms ao, a1, a2, a3, and a4, while option C has a total of six terms (from i = 0 to 5): a0, a1, a2, a3, a4, a5.
S, the obvious candidate is option A. So now evaluate the five terms corroborating that:

Therefore, option A is the answer
