Answer 1

choose the correct slope of the line that passes through the points (1 −3) and (3 −5)

Answer 2

what are the choices?!?!?!?

Answer 3

-1
1
0
1/2

Answer 4

sorry

Answer 5

what is the formula for slope, you have to remember it from now on

Answer 6

rise over run ???

Answer 7

okay what does it mean by rise? and what does it mean by run?

Answer 8

im new with this idk

Answer 9

rise is the y component, and run is the x component? does that make sense?

Answer 10

ok yes

Answer 11

okay so if your given two y components and to x components. How would you slope of that?

Answer 12

two x components*

Answer 13

\[slope=m=\frac{ y _{2}-y _{1} }{ x _{2} -x _{1}}\]

Answer 14

does that make sense?

Answer 15

sort of

Answer 16

so basically if you are given two co-ordinates. you take the y value of the second co ordinate and subtract it by the y value of the first co-ordinate. and then divide that by the x value of the second co-ordinate, subtract by the x value of the first co-ordinate.

Answer 17

and it always has to be the second minus the first

Answer 18

-2

Answer 19

that what you get for the rise right?

Answer 20

yes

Answer 21

okay now find the run

Answer 22

-1.5

Answer 23

nope, remember
rise: y2-y1
run: x2-x1
slope=rise/run

Answer 24

ok hold up let my try again

Answer 25

-2.5

Answer 26

is that what you got for the slope?

Answer 27

-2

Answer 28

?, okay can you tell me what you are calculating right now

Answer 29

rise=-2
run=2

Answer 30

then i divide and get 0
so answer wold be 0?

Answer 31

u there

Answer 32

you have to divide rise by run are you sure you got 0?

Answer 33

-1 got it

Answer 34

good job :)

Answer 35

thks

Answer 36

does it make sense now?

Answer 37

yup easier than i thought

Answer 38

thats good to hear :)
