Plzz help! Choose the system of equations which matches the following graph.
following..........?
here's the graph for the Q ^ @kidrah69 @They_Call_Me_Narii
A. x + 2y = −10 3x − y = 12 B. x − 2y = −10 3x − y = 12 C. x + 2y = −10 3x + y = 12 D. x − 2y = −10 3x + y = 12
it's a just use graphs
@CallMeKiki
@LegendarySadist
any guesses? @They_Call_Me_Narii
No. . I Dont Wanna Give U The Wrong Answer
well if you had a guess what would it be? @They_Call_Me_Narii
@alyssa_xo can you help?
the solution is the point where the graphs are equal the solution (graphically) is the point where the lines intersect find the point where (2,-6) satisfies both equations
also worth mentioning the line with a positive slope has a slope of 3 we can cancel c and d because when we get the line into y=mx+b form, our slope is -3 \(3x + y = 12 \\y=\color{red}{-3}x+12\)
ok I think it's either A or D am I right?
mhm
So would it be A ?
yeah. check your work by plugging in the point of intersection (i.e. the point on both lines)
ok thx for your help :) ^
