slope form y = mx + b; m is the slope

so for the first one 2 is the slope?
precal
  • precal
if the slopes are the same, the lines are parallel
anonymous
  • anonymous
ok try solving for y 7y+2x=4
anonymous
  • anonymous
I feel silly but what would be my first step?
anonymous
  • anonymous
subtract 2x from both sides
anonymous
  • anonymous
The slope would be -2?
anonymous
  • anonymous
for the first?
anonymous
  • anonymous
nope write the whole thing 1st equation slope is 2
anonymous
  • anonymous
ok..... so the second would be the same then?
anonymous
  • anonymous
no, try solving for y, will help u
anonymous
  • anonymous
oh my ok.. let me work this out.. Just a sec
anonymous
  • anonymous
It would be 4?
anonymous
  • anonymous
nope 7y+2x=4 subtract 2x from both sides
anonymous
  • anonymous
sorry I thought I did.. this is embaressing ... ok just a sec
anonymous
  • anonymous
For some reason I just keep getting 2

7y+2x=4 -2x -2x 7y = -2x + 4 is that correct?
anonymous
  • anonymous
(4-2x)/7
anonymous
  • anonymous
yes
anonymous
  • anonymous
correct one extra step y = -2/7x + 4/7 whats the slope
anonymous
  • anonymous
is it undefined?
anonymous
  • anonymous
y = mx + b m = -2/7

I dont see where I went wrong....

Oh ok I see that now. WOW how confusing... I hope I can handle the next on my own.. Thanks for your generous help...

Ok so how would I go about doing a question that asked me this... slope intercept equation of the line whose graph is parallel to y=2x-5 and has te y-interceot (0,9) There is no way I could do that one on my own!
anonymous
  • anonymous
they are parallel so the slope will stay the same y - y1 = m(x -x1) y - 9 = 2*(x-0) y - 9 = 2x +9 +9 y = 2x + 9
