Question

use each graph to solve the system of linear equations.
2.
3.
4.

Explanation:

Problem 2:

Step1: Find intersection point

The two lines cross at $(2, -3)$.

Step2: Verify solution

Substitute $x=2, y=-3$ into both lines' equations to confirm it satisfies both.

Problem 3:

Step1: Find intersection point

The two lines cross at $(4, 1)$.

Step2: Verify solution

Substitute $x=4, y=1$ into both lines' equations to confirm it satisfies both.

Problem 4:

Step1: Analyze line behavior

The lines are parallel (no intersection).

Step2: Determine solution type

Parallel lines never intersect, so no solution exists.

Answer:

1. The solution is $x=2$, $y=-3$ or the point $(2, -3)$
2. The solution is $x=4$, $y=1$ or the point $(4, 1)$
3. No solution (the lines are parallel and never intersect)
