7x9y=4 => slope = 7/9 the equation of the line will be y=mx+b 6=(7/9)*7+b and then solve for b

the line is parallel to the given line, so it has the same slope

ok good with this line y= 7/9x4/9 what is your slope m=?

hmm seems like you dont like an interaction question and answer,,... :D ok after getting the slope of this line y= 7/9x4/9 , also get the slope of parallel to this line then form an equation of line from the point (7,6) with that slope of parallel line.. ..

can u help me solve this problem please

im sorry the slope of parallel line is the same m1=m2 so you can form another line using this slope m1, using the point(7,6) and the formula y1y=m(xx1)

from y= mx + b y= 7/9x  4/9 what is the slope m?

try to compare the formula to the one you answered on y=7/9 x 4/9

would i have too subtract 7/94/9

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
by comparing the formula from y= mx + b y= 7/9x  4/9 what is the slope m? we know that b=4/9, what is slope m?
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
no you cant subtract because 7/9 x has an x with it and the 4/9 has no x.. so they are different terms
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
if it would be 7/9x  4/9 x then its ok to subtract but this time they are not.. :D go ahead you can ask me more question what do you want to know

from y= mx + b y= 7/9x +  4/9 we know that b=4/9,, what is slope m=?

I dont know how too get the slope. Confuse.

do i subtract 4/9 too both sides

i will give you more examples if y= 3x +4... the slope of this is m=3 and b=4 for f(x)=1/3 7 the slope of this line is m=1/3 and b=7

MauriceLong Group TitleBest ResponseYou've already chosen the best response.0
so the slope is 4/9

from y= mx + b y= 7/9x +  4/9 that is b=4/9,, what is m?

yessss : correct :D

so now that you know m=7/9, we also have the point (x1,y1)=(7,6); use that given to the formula yy1=m(xx1)

MauriceLong Group TitleBest ResponseYou've already chosen the best response.0
yy1=7/9(xx1)
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
correct but you also have to sub what is x1 and y1 (x1,y1)=(7,6); sub thius to what you have done you are getting closer :D
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
this is what you said the answer yy1=7/9(xx1) all you need to do is to sub what is x1 and y1 there
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
(x1,y1)=(7,6); sub this to your answer yy1=7/9(xx1)

if you have a point of (7,6) your x1=7 and y1=6... therefore this can be like this (x1,y1)=(7,6)
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
therefore plug those x1 =7 and y1=6 to your answer yy1=7/9(xx1)

y=7/9(x6)

y  y1 = 7/9 ( x  x1 ) y  ____ = 7/9 (x  ______)

MauriceLong Group TitleBest ResponseYou've already chosen the best response.0
y6=7/9(x7)
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
the point is (7 , 6) ( x1,y1) x1=7 and y1= 6 careful on negative sign, put the negative sign on 6... you are getting closer to the correct answer

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
y  y1 = 7/9 ( x  x1 ) y  ____ = 7/9 (x  ______) give it more try ill tell you if you are correct :D

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
your answer y6=7/9(x7) 6 is not correct because y 6=__?
 2 years ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
y  y1 = 7/9 ( x  x1 ) .... y  ____ = 7/9 (x  7) give it more try on the y, ill tell you if you are correct :D   6 is not= 6

mark_o. Group TitleBest ResponseYou've already chosen the best response.0
y  y1 = 7/9 ( x  x1 ) y  6 = 7/9 (x  7) try to simplify this more
