A. y = 3 over 2x − 3 B. y = 3 over 2x + 3 C. y = negative 2 over 3x + 23 over 3 D. y = negative 2 over 3x − 23 over 3

ok so we are going to use point slope form

do you know the point slope formula
laughoutloud

  • anonymous
is y2 -y1/x2-x1?
laughoutloud
  • laughoutloud
no that is the formula for finding slope the formula for point slope is \[y -y _{1}=m(x-x _{1})\]
anonymous
  • anonymous
Oh okay my bad so how do we do that ?
laughoutloud
  • laughoutloud
well they pretty much give you everything what is the slope?
laughoutloud
  • laughoutloud
*hint since it is parallel the slope are the same
anonymous
  • anonymous
the slope is 2?
laughoutloud
  • laughoutloud
is this how your equation looks \[y=\frac{ 2 }{ 3 }x+3\] is so then the slope is 2/3x
anonymous
  • anonymous
yeah that how it looks except the fraction is negative
laughoutloud
  • laughoutloud
oh okay sorry so the slope is -2/3x
anonymous
  • anonymous
its okay(: soo whats next
laughoutloud
  • laughoutloud
now you plug in the values the slope for m and the point (7,3) for x(1) and y(1)
anonymous
  • anonymous
so y - 3 = m(x-7) ?
laughoutloud
  • laughoutloud
yes but plug in the slope for m
anonymous
  • anonymous
Okay i changed the m to -2/3, now what cause im having a little trouble solving it
laughoutloud
  • laughoutloud
solve for y
anonymous
  • anonymous
7y times -2/3?
laughoutloud
  • laughoutloud
k idk what you did to get that lol but when you distribute you should get \[y-3=-\frac{ 2 }{ 3 }x-\frac{ 14 }{ 3 }\]
anonymous
  • anonymous
I got that i just dont know where to go from there
laughoutloud
  • laughoutloud
wait it should be \[y-3=-\frac{ 2 }{ 3 }+\frac{ 14 }{ 3 }\]
laughoutloud
  • laughoutloud
then combine like terms
laughoutloud

anonymous
  • anonymous
y-3=16/3
laughoutloud
  • laughoutloud
|dw:1440711463913:dw|
laughoutloud
  • laughoutloud
answer should be \[y=-\frac{ 2 }{ 3 }+\frac{ 23 }{ }\]
laughoutloud
  • laughoutloud
23 over 3
anonymous
  • anonymous
so 25/3?
laughoutloud
  • laughoutloud
sorry i made a mistake again \[y=-\frac{ 2 }{ 3 }x+\frac{ 23 }{ 3}\]
anonymous
  • anonymous
so what should i solve first
laughoutloud
  • laughoutloud
its done thats the answer
laughoutloud
  • laughoutloud
is it one of the choices
anonymous
  • anonymous
Oh i see my badddd, it is one of the choices...Thank youu!!
