Allow me to review before I start.  Inconsistent means there's no solution to the system of simultaneous equations, i.e. parallel lines.  Consistent means there's at least one solution.  Independent and dependent apply to consistent systems.  The former means exactly one solution (two lines in different directions which meet).  Dependent means an infinite number of solution; the two lines are really the same line.

1. We have two different slopes, lines in two different directions, so they'll meet in exactly one place.  That system is consistent and independent, the usual case.

2. We can write the first one y-3x= -2 and the second y-3x=+2.  These are parallel lines that are different, so no solution: inconsistent.

3.  The first equation is x+2y=4, same as the second. An infinite number of solutions.  Consistent and dependent.

By rewriting the 3 given systems, we will see that:

  • 1) Independent and consistent.
  • 2) Independent and inconsistent.
  • 3) Dependent.

Which types of systems do we have?

Let's analyze each system.

Let's look at the first one, we can rewrite it as:

y = 2x + 3

y = -x - 3

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

Now let's look at the second system, we can rewrite it as:

y = 3x - 2

y = 3x + 2

Here both lines have the same slope, so the lines never do intersect, meaning that the system is inconsistent and independent.

For the final system we have:

y = (-1/2)*x + 2

y = (-1/2)*x + 2

So, we have two equal lines, so this system is dependent.
