a system of equations with no solutions means ur lines will be parallel and will not intersect. A parallel line will have the same slope but different y intercepts.
y = 8x + 7...slope here is 8 and y int is 7
so any equation with a slope of 8 and a y int of anything other then 7 can be ur answer.
such as :
y = 8x + 8 or y = 8x - 12, or y = 8x + 5...
