Question

Find the slope of the line passing through the given points. Then tell whether the line falls, rises, is horizontal, or is vertical. (14,-3),(4,11)

Answer 1

Are you familiar with y = mx + b?

Answer 2

yes

Answer 3

i know how to find the slope i just dont know how to find out whether if it falls, rises that stuff

Answer 4

Okay, good, now, I'm going to simply plug each point into that formula:

-3 = 14m + b
11 = 4m + b

Are you with me so far?

Answer 5

yes

Answer 6

Okay, m is the slope, so I'm going to isolate b in both equations:

b = -3 - 14m
b = 11 - 4m

Do you see how I got that?

Answer 7

kinda

Answer 8

It takes a little practice to understand it, but now I'm going to set

b = b

to get:

-3 - 14m = 11 - 4m

Answer 9

Now all I have to do is solve for m:

-3 - 11 = 14m - 4m
-14 = 10m

-14/10 = m

- 7/5 = m

Answer 10

There we go

Answer 11

ok i was wait thats not right

Answer 12

You entered the answer as soon as I posted it, lol

Answer 13

kk i got that too

Answer 14

haha yeah

Answer 15

You shouldn't enter the answer so fast :P I guess I can take my own advice in that regard.

Answer 16

okay

Answer 17

Sometimes, I make typos, so you should wait at least one minute after someone posts their answer.

Answer 18

um ok

Answer 19

My fingers are not as bright as my brain

Answer 20

Sometimes, my fingers hit keys they shouldn't.

Answer 21

oh okay its a

Answer 22

all G

Answer 23

By the way,

If the slope is NEGATIVE, it FALLS
If the slope is POSITIVE, it RISES

Answer 24

always?

Answer 25

If something falls, it's always going down, right?
If a plane rises from the ground, it is always going up, right?

Answer 26

right

Answer 27

ohh i see

Answer 28

Yeah just think about a plane either taking a nose dive or lift off

Answer 29

ohh okay thank u!
