Answer 1

@Vandreigan

Answer 2

Whats the slope of the graphed line?

Answer 3

i have no idea.

Answer 5

\[slope = \frac{Rise}{Run}\]

or you can find two points and do this:
\[slope = \frac{Y_2 - Y_1}{X_2 - X_1}\]
with the x and y values of the points.

Answer 6

idk what the rise is and the run is... i missed a day at school and then i came home to do my extra math studies and i had the same study on my extra as i did on my school

Answer 7

Use the second equation, then. Find two points, plug in their x and y values as shown.

Answer 8

rise is up and down (y-axis) , run is left and right (x-axis)

Answer 9

ok so i found (2,0)

Answer 10

what would the slope of that be?

Answer 11

correct

Answer 12

Answer 13

2,0

Answer 14

so i divide 2 by 0?

Answer 15

because...

Answer 16

that is impossibru

Answer 17

No. Pick two points that are on the line, that you can easily tell the coordinates of.

Answer 18

2,1?

Answer 19

if you look at my original post on the comments it displays my options

Answer 20

Nope. The point (2,1) isn't on the line.

(0,1) is, though. Can you find another?

Answer 21

the slope will be negative because it goes diagonally up left...
choose 2 points and list their coordinates below... ex (x,y)

Answer 22

hmm...

Answer 23

im writing this into an e^2 and it's harddddddd

Answer 24

e^2 =equation

Answer 25

why?

Answer 26

i come from the garrys mod community and i mess around alot with wiremod and expression^2

Answer 27

and as a shorthand we just write e^2

Answer 28

just dont rely on video games... here we actually do math there they mess around

Answer 29

wiremod is very complex... go look it up

Answer 30

ill post a link

Answer 31

Answer 32

you write out code in lua and implement it directly into the game

Answer 33

it involves a ton of calculus and algebraic problems

Answer 34

no im good...

one coordinate is (0,1) another is (2,-2) now insert into equation

\[m= \frac{ rise }{ run }\]

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

Answer 35

guys this will sound very lame but i have to go due to an event i planned a week earlier... sorry ;^;

Answer 36

No problem. Enjoy!

Answer 37

ok we'll just continue when you get back...
