You can put this solution on YOUR website!
x-2y=6 or -2y=-x+6 or y=-x/-2+6/-2 y=x/2-3 (Red line)
To find 2 points to plot you need to set y=0 & solve for x. Thus:
0=x/2-3 or x/2=3 or x=6 when y=0 (6,0) & the y intercept is (0,-3)
x+4y=5 or 4y=-x+5 or y=-x/4+5/4 (Green line)
0=-x/4+5/4 or -x/4=-5/4 or -4x=-20 orx=-20/-4 or x=5 when y=0 (5,0) & the y intercept=(0,5/4).
