Question

find the equation of the line having the given slope and containing the given point m=6/7,(8,-3) PLEASEEEE HELP

Answer 1

y-y0 = m(x - x0)

this is the formula you use. you put 6/7 for m, and you put
x0: 8
y0: -3

then, expand the parentheses and bring into standard form

Answer 2

this is what i got y+3=6/7(x-8)

Answer 3

very good

try to expand the parentheses

Answer 4

hmm y+3=6/7x
and then do i multiply 6/7 by -8 ? its kind confusing

Answer 5

it is difficult. and yes, you multiply 6/7 with -8

when multiplying you just multiply the upper term, so 6 x -8 = -48
for the sign: negative times positive = negative

we just carry over the denominator when we are done and get:
-48 / 7

Answer 6

so is it y+3=6/7x-48/7 ? or do i subtract 3 from both sides ?

Answer 7

you also subtract three from both sides as the final step :)

then it's in standard form y=mx +b

Answer 8

so its y=6/7x-51/7 is the final answer? and thank you so much (:

Answer 9

something like that .if you are subtracting a number from a fraction
you must first make that number have the same denominator

Answer 10

i dont get it ;(

Answer 11

applying the operation to the upper term only works for multiplication exlusively
in case of add/subtract:
\[\frac{-48}{7} - 3 =\frac{-48}{7} - \frac{3 \times 7}{7}\]\[\frac{-48}{7} - \frac{21}{7} = \frac{-69}{7}\]

Answer 12

in other words you need the same denominator for addition/subtraction!!

Answer 13

so i put -69/7 instead instead of -51/7 ? thats it?

Answer 14

yes

you can extend "3" into "21/7" and then subtract the 21/7 from what we had
an you would get the same result

Answer 15

3/4 - 1/4 = 2/4 <- this is a rule

3/4 - 1 = <- this needs the first denominator first
3/4 -4/4 = -1/4 <- aha!

Answer 16

you cant do everything at the same time
this is our result

y=6/7x-69/7

Answer 17

so what is the final answer ? cause im lost D:

Answer 18

y=6/7x-69/7

Answer 19

okay thank you alotttt (: c: :3
