y=-2x%2B1....eq.1
4x%2B2y=2+.....eq.2
____________________________substitute y from eq.1 to eq.22
4x%2B2%28-2x%2B1%29=2+.....eq.2.........solve for x
4x-4x%2B2=2+
4x-4x=2-2+
0=0+ so, this system is depended; the two lines are identical (one lies perfectly on top of the other) and intersect at all points of both lines
