Solve the system of equations y = 2x + 3 and 4x - 2y = -6 using a graphical method.
2 answers:
We have that
<span>y = 2x + 3 -----> 2x-y=-3----> multiply by 2------> 4x-2y=-6-----> equation 1
4x - 2y = -6 ------> equation 2
equation 1 and equation 2 is the same
using a graph tool
see the attached figure
points A, B and C </span><span>belongs to the line---------> </span><span>they are system solutions</span><span>
the answer is
options A, B, C and D are corrects</span><span> </span>
