Question

CAN SOMEONE REALLY HELP ME WITH THESE SLOPE QUESTIONS
4. Determine the slope between the points (-1, 0) and (-2, 3)

Answer 1

slope = rise over run, which is "change in y coordinates divided by change in x coordinates"

using your two points as (x1, y1) and (x2, y2),
slope = (y2 - y1) / (x2 - x1)

You just put your actual coordinates in, subtract each part, then divide.

Answer 2

so i just write this (3-0) / (-2-3)
(0)/(1)

Answer 3

@JakeV8 ummm so?

Answer 4

I think you mixed up the part on the bottom...

(3-0) was correct for the top.

The bottom should have been -2 -(-1).

Answer 5

ok so its -3?

Answer 6

I get: (3-0) / (-2 - (-1)) = 3 / (-1) = -3

Is that how you did it too? If so, that's correct.

Answer 7

yeah so wat u do after tht?

Answer 8

@JakeV8 ?

Answer 9

That's all there is... you found slope = -3. That's all this problem is asking you.

Answer 10

ok ty

Answer 11

oh ok

Answer 12

is this the same thing too? 5.Determine the slope between the points (-1, -5) and (5, 4)

Answer 13

yes, same thing... just repeat with those points. Be careful subtracting negatives though... that's where errors start. Give it a try and I'll check it.

Answer 14

ok

Answer 15

wait i think this is wrong look at the numbers
slope = rise over run
(x1, y1) and (x2, y2), slope = (y2 - y1) / (x2 - x1)
(3-0) / (-2 - (-1)) = 3 / (-1) = -3

Answer 16

why does it seem wrong?

Answer 17

because 4. Determine the slope between the points (-1, 0) and (-2, 3)

Answer 18

x1=-1 y1=0 x2=-2 y2=3

Answer 19

oops!!! sorry, my drawing is all wrong :(

Answer 20

that's embarrassing... let me fix it.

Answer 21

lol so was my answer wrong or right?

Answer 22

I think I need a snack or something... my brain appears to have quit :(

Answer 23

so is this right so far? (x1, y1) and (x2, y2), slope = (y2 - y1) / (x2 - x1)
(4-5)/(5-(-1))

Answer 24

(-1),(4)

Answer 25

One more try on your #4, no drawings... slope between (-1, 0) and (-2, 3) is:

rise / run = (3 - 0) / (-2 - (-1) ) = 3 / (-1) = -3

It goes up 3 for every one unit it moves to the left. That's correct... sorry for the drawing confusion.

Answer 26

I think you messed up on the negatives...

5.Determine the slope between the points (-1, -5) and (5, 4)

rise / run = (4 - (-5) ) / (5 - (-1) )

Answer 27

(9),(6)?

Answer 28

yes, but remember, it's a fraction, not a point... so you have slope = 9/6

You can reduce that fraction to 3/2.

Slope is like a rule that says "go up 3 for every 2 you go to the right". Or, "rise 3 and run 2".

Answer 29

If you "rise 3 and run 2" three times in a row, you can step from (-1,-5) up to (5,4).

Answer 30

yeah so u just divide it by 3

Answer 31

@JakeV8 so the slope = 3/2

Answer 32

yes, that's correct.

Answer 33

ok lol was the first question right too?

Answer 34

yes, it was just my drawing that was messed up.

Answer 35

ok what about this one Find the slope of the line graphed below.

Answer 36

@JakeV8 did u get it?

Answer 37

yes, I see it. What do you think it is? Rise over run... you just pick some point to start at and count the rise and run to some other point. An easy way is to choose where it crosses the x-axis on the left side, and count rise and run up to where it crosses the y-axis in the middle.

Answer 38

(1,0)?

Answer 39

Um, no... remember slope is a number, often a fraction... it isn't an ordered pair.

If you want, you could calculate it like we did earlier... choose those same 2 points...
(-3,0) and (0,5) then do rise over run.

Answer 40

oh those are two points oon the line >.<

Answer 41

@JakeV8 what you do after you find those points?

Answer 42

you can find slope, just like you did earlier...
slope = rise/run = (5-0) / (0 - (-3))

Answer 43

3-0/-2+1=slope
slope=-3

Answer 44

I don't follow where you got those points. I think the easiest points to use are (-3,0) and (0,5), so slope = rise/run = (5-0) / (0 - (-3))

Answer 45

We're talking about two or three different problems in this thread now... confusing...

Maybe time for a new question posting if there are more slope questions.

Answer 46

wait so it = (0,3)?

Answer 47

@JakeV8

Answer 48

@pkjha3105 can u write out it out 4 me?

Answer 49

slope=y2-y1/x2-x1
slope=3-0/-2+1
slope=-3

Answer 50

@pkjha3105 ty ! can u help me with 2 more please :)
