Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3x + 3. y = 3 over 2x − 3 y = 3 over 2x + 3 y = negative 2 over 3x + 23 over 3 y = negative 2 over 3x − 23 over 3

ok, I recommend using the slope-intercept equation. do you know what that one is?

y=mx+b?

perfect, so they gave you an x and a y when they said it passed through (7,3) so start by plugging that in.

3=m(7)+b?
anonymous
  • anonymous
good, now if 2 lines are parallel, what does that mean for their slopes?
anonymous
  • anonymous
they're the same
anonymous
  • anonymous
so plug that in

y = negative 2 over 3x + 23 over 3?
anonymous
  • anonymous
keep what you had before...

What do you mean by plugging the fact that they have the same slopes then?
anonymous
  • anonymous
Oh ok so 3=-2/3(7)+b
anonymous
  • anonymous
great, now solve for b :)
anonymous
  • anonymous
How lol
anonymous
  • anonymous
ohhh b=23 over 3?
anonymous
  • anonymous
yup :) so now go back to y=mx+b
anonymous
  • anonymous
plug in the slope and the y-intercept and you have your equations.
anonymous
  • anonymous
so it would be the third option
anonymous
  • anonymous
yes. great work!

lol thanks i got some more
