Use the graph to state the solution for the system. x – y = 4 (line a) x + y = 4 (line b) A. (0,4) B. (4,0) C. (-4,0) D. (0,-4)
this is the graph! http://static.k12.com/calms_media/media/213000_213500/213096/1/adbd565410979272c1f30c00abb475ba5a33c67b/ALGTests_L2_S1_U8_Q2v2Stem.gif
sure but i would pefer u used the graph
Where the two lines intersect is your solution.
@leutz13 did u get it?
no im trying to take three test at once
oh ok lemme know if u have trouble figuring out the point of intersection :)
yeah i am having trouble
wait no srry i miss read that
the point of intersection is bout all i know
that's the answer but which ordered pair represents the intersection?
yeah thats what i cant figure out
so u know what the x-axis is right?
yes
great! what number do u see on the intersection, that is on the x-axis?
4
awesome! :D what about for the y-value? is there any number ?
there is but i dont know how that one works
