Answer:

1.  Consistent independent.

2.  Coincident

3.  Inconsistent.

Step-by-step explanation:

4x + y = 8

x +  3y = 8   Multiply this equation by -4:

-4x - 12y = -32

Adding this to the first equation:

-11y = -24 giving y = -24/-11 = 2.18

Substituting in the first second equation:

x + 3(2.18) = 8 giving x = 1.46.

So this system of equations has roots (1.46, 2.18)  and is consistent independent.

2.

-4x + 6y = -2

2x - 3y = 1   Multiply this by -2:

-4x + 6y = -2

So these 2 equations are the same and will give the same graph on the coordinate plane, and so has:

Infinite solutions  and is coincident.

3.

5x - 2y = 4

5x - 2y = 6

We can see immediately that this system of equations has NO Solutions.

If we subtract the 2 equations  we get:

0 = -2 which is of course, absurd.

Classification Inconsistent.
