Example of a system of inequalities that has no solution.

Ok got it

so reemember that if 2 lines are paralell, they never intersect ad therefor have nosolution intersection

so 2 lines that are paralel have the same slope
lets say slope=3
y=mx+b
y=3x+b
change b so it is different
y=3x+7
y=3x+5
if we graphed those we get 2 paralel lines, then we made the 7 one greaer

y>3x+7
y<3x+5
there is no solution
