Solve each equation separately:

(-1, 3) Has to be a point that fits both equations

y = 2x + ____

Plug in Values:

3 = 2(-1) + ____

3 = -2 + ____

___ = 5

First Blank: 5

y = ___x - 1

Plug in Values:

3 = ___(-1) - 1

4 = ___(-1)

___ = -4

Second Blank: -4

the first one you plug in 3 for y and -1 for x:

3=2(-1)+? plug in x&y coordinates

3= -2 +? multiply -1×2

5 = ? add 2 to both sides

the second one you do the same:

3=?(-1)-1 plug in x&y coordinates

4=?(-1) add 1 to both sides

-4=? divide by -1

Need help what are the classifications of each system

ratelena [41]

You can graph them on Desmos, then use this attachment to find out the classification.

In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.

In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.

In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
