Explanation:

Step1: Analyze Graph 1

The two lines intersect at one point.

Step2: Analyze Graph 2

The two lines are parallel (no intersection).

Step3: Analyze Graph 3

The two lines intersect at one point.

Step4: Analyze Graph 4

The two lines intersect at one point.

Step5: Analyze Graph 5

The two lines intersect at one point.

Step6: Analyze Graph 6

The two lines intersect at one point.

Step7: Analyze Graph 7

The two lines are parallel (no intersection).

Step8: Analyze Graph 8

The two lines are the same (coinciding).

Step9: Analyze Graph 9

The two lines intersect at one point.

Answer:

  1. How many solutions? one at $(-2, 2)$

How do you know? Lines intersect once.

  1. How many solutions? none

How do you know? Lines are parallel, no overlap.

  1. How many solutions? one at $(1, 2)$

How do you know? Lines intersect once.

  1. How many solutions? one at $(-2, -1)$

How do you know? Lines intersect once.

  1. How many solutions? one at $(0, -3)$

How do you know? Lines intersect once.

  1. How many solutions? one at $(2, -1)$

How do you know? Lines intersect once.

  1. How many solutions? none

How do you know? Lines are parallel, no overlap.

  1. How many solutions? many

How do you know? Lines are identical, infinite overlap.

  1. How many solutions? one at $(3, 0)$

How do you know? Lines intersect once.
