Find the slope and y-intercept of the line through the points (-3,-4) and (0,-1)​

Answers

Answer 1
Answer:

Answer:

Slope=1, y-intercept=-1.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-4))/(0-(-3))

m=(-1+4)/(0+3)

m=3/3

m=1

y-(-4)=1(x-(-3))

y+4=x+3

y=x+3-4

y=x-1

y=mx+b where m=slope and b=y-intercept

so you have slope of 1 and y-intercept of -1

6

-
3

Answers

4-3. hope that helps.
Simple...

you have

4-6=?
and
4-3=?

Well, if you know anything about negatives...you know that 6 is a bigger number than 4; and that if you subtract it, it becomes a negative...

4-6= -2
and
4-3=1

Now, which one is bigger?

Fairly easy...when a number is negative..that means it less than 1. Even smaller than 1. 

So, that being said 4-3 is obviously bigger.

Thus, your answer.

Whys is it helpful to write a number as a product of primes

Answers

It is important to write a number as a product of primes because on many tests, you will be asked to write the "prime factorization". Also, any time you are asked a question about multiples or factors, you bet using prime factorization will get you your answer quicker!

Every function is a relation. However, not every relation is a function. In a function, there cannot be two lists that disagree on only the last element.

How do you graph y-2x=2

Answers

turn it into y=mx+b form so it is y=2x+2 the b=2 so y intercept is (0,2) and the slope is 2, do a rise of two and a run of 1 and then connect the dots

On the school playground, the slide is due west of the tire swing and due south of the monkey bars. If the distance between the slide and the tire swing is 9 meters and the distance between the tire swing and the monkey bars is 15 meters, how far is the slide from the monkey bars?

Answers

It would be 12 meters :)
Explanation: You woulde use Pythagorus theorum which is a2 + b2 = c2 because the slide, tire swing and monkey bard create a triangle.

15x15 = 225
9x9 = 81
225-81 = 144
Square root of 144 = 12 meters

a van has room for 6 students and 2 teachers.how many vans are needed for a total of 48 students and 16 teachers?

Answers

2 vans = 12 students and 4 teachers
4 vans = 24 students and 8 teachers
6 vans = 36 students and 12 teachers
8 vans = 48 students and 16 teachers

Basically saying:
___ x 6 = 48
___ x 2 = 16
Since the answer to both of these equations is 8, then 8 vans are needed to carry 48 students and 16 teachers.

*If you need a better explanation of this process or have any questions or comments, you can ask me at any time, I'd be happy to help!
the answer is 8 students and 8 teachers
