Question 1.
First solve for slope: $\frac{0-8}{8-0} = \frac{-8}{8} = -1$
Point-slope formula is: y2 - y1 = m(x - x1)

where m = slope.
Plug in values for PS form: y - 0 = -1(x - 8)

So the answer is Choice 2.

Question 2.
Choice D.
Points given: (-10, -7) and (3, -7)
Both y -intercepts are equivalent to -7

Question 3.
Choice A.
Points given: (2, 4) and (2, -7)
Both x - intercepts are equivalent to 2

Question #1

We can see that the (y)

axis would then be (0,8), but then as it would then drop down, we can see that it would change by (8,0). This would be clear to show us that the equation would then be (y=-x+8)

because as the line decreases, it would be added by 8.

Your $\boxed{\bf{y-0=1(x+8)}}$

Question #2

We can see that first, we would start off in the (y)

axis on this part, and then, we can see that (3,-7) would be considered a positive form. And therefore, we would want to find the equation.

$(3-10) \ =-7$

Your $\boxed{\bf{y=-7}}$

Question #3

We first start off on the (y) axis of course, mainly because this would be the only thing that we would contain to have. And then after, we would then compare these both, as we would then know that the difference between both 4 and 2 would then end up to be 2. And therefore, that would then give us our answer as 2.

Your $\boxed{\bf{x=2}}$

I hope this helps you!

Answer from: Quest

your exact question is kind of difficult to understand, so maybe an example will explain what you're supposed to do? i'll work through the first problem on the worksheet.

suppose you have a tray of 652 brownies, and you have 5 friends that you want to feed without picking favorites. how many brownies can you dole out to each of your friends in equal amounts? how many will be left over for you to eat?

what you're doing here is finding a way to arrange the number 652 as the sum of integer multiple of 5 and some remainder: $652=5q+r$

here $q$ ("q" for quotient) is the number of brownies each of your friends get, and $r$ is the remainder. that's the basic idea behind division.

we break up the number 652 into parts so that the leading digit stands on its own:

652 = 600 + 52

first we check if it's possible to hand out exactly 100 brownies to each friend. with 5 friends, this means we want to know if we can take out 500 brownies from the tray. we can do this 1 time because we have 600 brownies to take from, and when we do that we're left with 100 + 52 brownies to divvy up. so we know that

652 = 1*500 + 152

next we want to know if it's possible to hand out exactly 10 brownies per friend. if we can, we have to remove 50 brownies from the tray each time until we can't. we have 152 brownies left, and we know that 3(50) = 150, so

152 = 3*50 + 2

now we have 2 brownies left in the tray. is it possible to hand 1 out to each of your 5 friends? no, you'd need a minimum of 5 brownies to do that. so the last 2 are yours.

putting everything together, we found that

652 = 1*500 + 3*50 + 2

and we can rearrange this to write

652 = 5*100 + 5*30 + 2

652 = 5(100 + 30) + 2

652 = 5*130 + 2

so $q=130$ and $r=2$ .

you might be more accustomed to the table depicting the algorithm. that's just a compact way of organizing what we've done above. you can consult the image i've attached below.

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
