solve the system by graphing {2x+y=-7 {-3x+2y=14
y=-2x-7 y=3/2x+7 okay so you would graph that and see where the line crosses|dw:1323934096889:dw| which by filling out the graph it would be at x=-4 and y=1
hmm it says solve by graphing. So im not sure how it is supposed to look . post this in the chat and see if anyone else understands how the answer is supposed to be
nevermind. I was wrong. Can you show me exactly what you did please
well I just put the equations in slope intercept form which Im sure you know how to do. And I graphed each equation. And where the 2 lines intersect is where your solution is
show me every step you did. even the steps of turning it into slope intercept form please
okay but the you can make your own graph because as you can tell by my draxing I am not a good artist
2x+y=-7 y=-2x-7 -3x+2y=14 2y=3x+14 y=(3/2)x+7 |dw:1323935094857:dw|
the point where the 2 lines meet in that circle is (-4,1)
I'm lost. I need every step when it comes to working it before the graphing.. the graphing i get , i just need the work.
2x+y=-7 y=-2x-7 -3x+2y=14 2y=3x+14 y=(3/2)x+7
immmm still lost
hmmm i dunno what i can do differently. Maybe someone else will check this out when more people come online in a few hours and show ya in a better way. Sorry =(
i just font get how you chnaged the second equation/:
subtract 3x then divde everything by 2 to get y by its self
