Answer 2

To determine which points satisfy the equation \( 2x + y = 6 \), we can substitute the \( x \) and \( y \) values from each point into the equation and check if it holds true.

1. For the point \( (6, 2) \):
\[
2(6) + 2 = 12 + 2 = 14 \quad \text{(not a solution)}
\]

2. For the point \( (-2, 2) \):
\[
2(-2) + 2 = -4 + 2 = -2 \quad \text{(not a solution)}
\]

3. For the point \( (4, -2) \):
\[
2(4) + (-2) = 8 - 2 = 6 \quad \text{(solution)}
\]

4. For the point \( (0, 6) \):
\[
2(0) + 6 = 0 + 6 = 6 \quad \text{(solution)}
\]

5. For the point \( (5, -8) \):
\[
2(5) + (-8) = 10 - 8 = 2 \quad \text{(not a solution)}
\]

6. For the point \( (6, -6) \):
\[
2(6) + (-6) = 12 - 6 = 6 \quad \text{(solution)}
\]

The points that are solutions to the equation \( 2x + y = 6 \) are \( (4, -2) \), \( (0, 6) \), and \( (6, -6) \).

### Plotting the Points
- **(4, -2)**
- **(0, 6)**
- **(6, -6)**

### Equation of the Line
To draw the line through these points, we can express the equation in slope-intercept form \( y = mx + b \). The equation \( 2x + y = 6 \) can be rewritten as:
\[
y = -2x + 6
\]
Where the slope \( m = -2 \) and the y-intercept \( b = 6 \).

### Summary
The three points that are solutions to the equation \( 2x + y = 6 \) are:
1. \( (4, -2) \)
2. \( (0, 6) \)
3. \( (6, -6) \)

After plotting these points and drawing the line, you'll clearly see they all lie on the line \( y = -2x + 6 \).

Answer 3

Here are two additional solutions to the equation \( 2x + y = 6 \):

### New Solution #1
Let's choose \( x = 1 \):
1. Substitute \( x = 1 \) into the equation to find \( y \):
\[
2(1) + y = 6
\]
\[
2 + y = 6
\]
\[
y = 6 - 2 = 4
\]
Therefore, New Solution #1 is \( (1, 4) \) because when you plug it into the original equation \( 2(1) + 4 = 6 \), the equation simplifies to \( 2 + 4 = 6 \).

### New Solution #2
Let's choose \( x = 2.5 \):
1. Substitute \( x = 2.5 \) into the equation to find \( y \):
\[
2(2.5) + y = 6
\]
\[
5 + y = 6
\]
\[
y = 6 - 5 = 1
\]
Therefore, New Solution #2 is \( (2.5, 1) \) because when you plug it into the original equation \( 2(2.5) + 1 = 6 \), the equation simplifies to \( 5 + 1 = 6 \).

### Summary of New Solutions
- **New Solution #1**: \( \left(1, 4\right) \)
- **New Solution #2**: \( \left(2.5, 1\right) \)

Both points satisfy the equation \( 2x + y = 6 \).
