we have that

case 1
3x-7y=9
-4x+5y=1
using a graph tool
the solution is the point (-4,-3)------------------> one solution

case 2
y=6x-2
y=6x-4
two parallel lines
the system has no solution---------------> zero solution

case 3
-5x+y=10
-25x+5y=50
is the same line----------------> infinite solutions

the answer is
see the attached figure
