Question

Help with the following: Find an equation of the line passing through each pair of point. Write equation in the form Ax=By=C

Answer 1

what are the points?

Answer 2

oh sorry, there (-1,3) and (-2,-5)

Answer 3

And I assume u meant Ax + By = C

Answer 4

yes, sorry

Answer 5

so first we find the slope:
M = (-5-3)/(-2+1) = -8/-1 = 8

Answer 6

Wait can you still stay on mines lemme jus re do it and check to see if i get it rite..plz

Answer 7

okay

Answer 8

Where did you get -2+1, is'nt it suppose to be -2-1?

Answer 9

-2 - (-1) = -2 + 1

Answer 10

oh okay, wait..;plzz i really need help

Answer 11

i will.. just yell at me in chat if im not here

Answer 12

okay

Answer 13

okay i got the slope which i 8.. Then how to i put it in the ax+bx=c form

Answer 14

okay now i would do this:
y-y1 = M(x-x1)
y-3 = 8(x+1)

Answer 15

then simplify:

Answer 16

SO its y-3=8x+8

Answer 17

How do i simplify

Answer 18

y -3 = 8x + 8
-8x + y = 8+3
-2x + y = 11

Answer 19

So this is in form:
Ax + By = C, where
A = -2; B = 1 and C = 11

Answer 20

How did you simplify??? And i keep getting -11=8x-y

Answer 21

y -3 = 8x + 8
subtract 8x and add 3 from and to both sides:
y - 8x - 3 + 3 = 8x - 8x + 3 + 8

Answer 22

woops sorry that 2 was supposed to be an 8

Answer 23

y - 8x = 11

Answer 24

in the back of my book it gives me 8x-y=-11

Answer 25

its the same thing, just multiply thru by negative 1... both of us are right

Answer 26

so either way 8x-y=-11 and y-8x=11 are correct?
