Giving Medals and Fanning whoever can give me the correct answer! Write a system of inequalities for the graphs. http://imgur.com/41IdtCV http://imgur.com/A0IcxWj
HOw many do you need?
I need two inequalities for each link.
do u know the difference between dotted line and solid line?
Yes
what i do is look for y intercept and x intercept ....while the other variable is 0.... for example i plug y = 0 , x + y solid bar sign 3.... for the dotted line x sign (what coordinate of x does it cross when y =0)
for the solid line on the first one I got y ≥ -x + 1. How do I find the second one if it's vertical ?
when i plug 0 in y i get 0 + x greater than 3 ok that is accutrate then check other variable x = 0 then 0 + y greater than 3 ok so first equation should be x + y >= 3
vertical line is on the x axis so for every x that is on that line is greater than 5
x > 5 ?
yes because dotted line so x > 5
:D
So for the other one, I turned them into equations: y = 3/4x + 3 and y = 1/5x + 1
i had 5y + x >= 5....... all but the sign i think u got it.... x + 3y >= 4 i think
Are those the last two answers or ?
yeah
but y = is better form
Thanks so much for all the help! :D
your right it should be y = -3/4 x + 3 good job
