observe that one line is rising, and the other is falling and both have same magnitude of slope : 1
ganeshie8
  • ganeshie8
can u find the equations ?
anonymous
  • anonymous
one could be y=x+1 and y=2x-2? @ganeshie8
ganeshie8
  • ganeshie8
very good :) almost correct !!

woohoo! where did i go wrong? :)

  • ganeshie8
since it is falling, the slope is -1 for that line

  • anonymous
oh, i see where i had gone wrong!
ganeshie8
  • ganeshie8
once we have the equations, its easy to write the inequalities :) do u knw how ?
anonymous
  • anonymous
no, thats where i get stumped :( do you mind explaining? :)
ganeshie8
  • ganeshie8
sure :) its easy actually. lets find inequality for rising line y = x+1
ganeshie8
  • ganeshie8
look at the shading, is it UP or DOWN ?
anonymous
  • anonymous
its going up
ganeshie8
  • ganeshie8
shading is going up, so simply replace = wid \(\ge\)
ganeshie8
  • ganeshie8
the inequality corresponding to y = x+1 wud be, \(y \ge x+1\)
anonymous
  • anonymous
so the first equation would be y ≥ 1 since it goes up
ganeshie8
  • ganeshie8
Yes !
anonymous
  • anonymous
oh x+1!
anonymous
  • anonymous
wow that is easy! so the second would be y >x-2?
ganeshie8
  • ganeshie8
Yes :) next, look at the shading of second equaiton : y = -x-2
ganeshie8
  • ganeshie8
Correct :) you're super fast !!
ganeshie8
  • ganeshie8
second inequality is actually y >-x-2
ganeshie8
  • ganeshie8
dont forget the negative sign
anonymous
  • anonymous
haha i try! math is like my kryptonite! thank you so much for the easy to understand explanation and the help, you're awesome! :) @ganeshie8 & that's right! i forgot the negative sign!

lol np :)
