find the equations of lines first
observe that one line is rising, and the other is falling and both have same magnitude of slope : 1
can u find the equations ?
one could be y=x+1 and y=2x-2? @ganeshie8
very good :) almost correct !!
woohoo! where did i go wrong? :)
since it is falling, the slope is -1 for that line
oh, i see where i had gone wrong!
once we have the equations, its easy to write the inequalities :) do u knw how ?
no, thats where i get stumped :( do you mind explaining? :)
sure :) its easy actually. lets find inequality for rising line y = x+1
look at the shading, is it UP or DOWN ?
its going up
shading is going up, so simply replace = wid \(\ge\)
the inequality corresponding to y = x+1 wud be, \(y \ge x+1\)
so the first equation would be y ≥ 1 since it goes up
wow that is easy! so the second would be y >x-2?
Yes :) next, look at the shading of second equaiton : y = -x-2
Correct :) you're super fast !!
second inequality is actually y >-x-2
dont forget the negative sign
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 :)
