Which equation can be represented using the number line? A number line going from to 1 in increments of one-eighths. Arrows go from each mark
on the line to the next up to three-fourths.

Three-fourths divided by one-eighth = 6

One-eighth divided by three-fourths = 6

6 divided by three-fourths = one-eighth

6 divided by one-eighth = three-fourths

When a system of equations has no solutions it called an inconsistent system of equations.

When you graph the equations, you will find that they will be parallel to one another. In other words, they won't intersect. On the other hand, a system of equations with one solution when graphed will have a point where they intersect. That intersection is the solution to the system of equations.
