Question

how do you find the equation for (2,4) and (3,1)

Answer 1

first u have to find the slope (do u know how?)

Answer 2

yes i believe its 5

Answer 3

ok let me check, 1-4/3-2 = -3/1 =-3

Answer 4

how do u find the slope??

Answer 5

or how did you*** sorryy

Answer 6

i did -1 -4 / 3 -2 = -5/1 x -1 = 5

Answer 7

why did u do the 1 negative??

Answer 8

the one in (3, 1) is actually negative sorry

Answer 9

oh okay lol! so the slope is -5

Answer 10

oh kat so what do i do after that?

Answer 11

okay u pick of any of the points u have ( ill pick (2,4) ) to find the y-intercept for the equation ill show u how! :)

Answer 12

yay thank you soo much

Answer 13

y=mx+b u want to find the B ok? ok

^ ^
slope y-intercept <--- i guess u know this right?
(lol ill write the y=mx+b alot so just dont get surprised)

y=mx+b , m(slope)=-5 , b=(2,4) (x,y) ok now u have to substitute the 2 by x and the 4 by y to find the y-intercept

y=mx+b
^ ^ ^
4=-5(2)+b , ( now u just have to find B)
4=-10+B
10+4=B
14=B , (OK THE Y-INTERCEPT IS 14)

so the equation u have is y=-5x+14

did u understand anything? if yes im so gglllaaddd!!! / if no just tell me what u didnt understand!! :)

Answer 14

i get it thank uuu sooo much :))

Answer 15

no problem chlojo7!!! :D :D
