Explain, in complete sentences, how you would use the graphing method to solve the following system of inequalities and what the final solution will look like on the coordinate plane. x – 2y –8 7x + y < –6
youv lost me already, sorry
lol i've lost myself too.. lol it's ohk
wat the heck is the graphing method?
What's the first equation. Is there an = missing?
oh whoops it's supposed to be x - 2y *greater than or equal to* -8
Does x – 2y –8= 7x + y < –6 .?
idk i dont think so.. /: sorry this is rly confusing for me too.. i haven't learned this stuff yet.. it's a pre-test
Well, its quite simple. Plot x-2y+8 =0. You can do that by equating x to zero and calculate y. That gives you a point (0,y). Next put y=0 and find x. You get the second point (x,0). Draw a line between these two points on the graph. Do the same thing for the next equation and draw a line. The intersection point is your result :)
thank you! c: I'll try to do this.. This helped me understand it more thank you a lot(:
