Given Line Eqn, 2x%2By=4

Let y=0:
2x%2B0=4 ---> cross%282%29x%2Fcross%282%29=cross%284%292%2Fcross%282%29
red%28x=2%29
Point (2,0)

When y=1:
2x%2B1=4
2x=4-1=3 ---> cross%282%29x%2Fcross%282%29=3%2F2
red%28x=3%2F2%29
Point (3/2,1)

When y=2:
2x%2B2=4
2x=4-2=2 ---> cross%282%29x%2Fcross%282%29=cross%282%291%2Fcross%282%291
red%28x=1%29
Point (1,2)

When y=3:
2x%2B3=4
2x=4-3=1 ---> cross%282%29x%2Fcross%282%29=1%2F2
red%28x=1%2F2%29
Point (1/2,3)

What if when x=0:
2%280%29%2By=4
red%28y=4%29
Point (0,4)

When x=1:
2%281%29%2By=4
y=4-2=red%282%29
Point (1,2)

*There are infinite number of solutions ,we just illustrated few.
Let us put the points in the graph:
