Chris can use **Zoom** to make the diagrams easier to read. Zooming in will enlarge the diagrams, making the details more visible.

To solve the system of equations using the substitution method, we can start with the first equation:

1. \( 2x + 3y = 4 \)

From this, we can express \( y \) in terms of \( x \):

\[
3y = 4 - 2x
\]
\[
y = \frac{4 - 2x}{3}
\]

Now, we will substitute \( y \) into the second equation:

2. \( -4x - 6y = -8 \)

Substituting \( y \):

\[
-4x - 6\left(\frac{4 - 2x}{3}\right) = -8
\]

Distributing the -6:

\[
-4x - \frac{24 - 12x}{3} = -8
\]

To eliminate the fraction, multiply the entire equation by 3:

\[
-12x - (24 - 12x) = -24
\]

Simplifying further:

\[
-12x - 24 + 12x = -24
\]
\[
-24 = -24
\]

This statement is always true, which indicates that the two equations represent the same line. Therefore, there are **infinite solutions** to this system of equations.

The correct response is: **infinite solutions**.

To solve the system of equations using the substitution method, let's start with the first equation:

1. \( x = y - 4 \)

Now we can substitute this expression for \( x \) into the second equation:

2. \( x + 8y = 2 \)

Substituting \( x \):

\[
(y - 4) + 8y = 2
\]

Now simplify the equation:

\[
y - 4 + 8y = 2
\]
\[
9y - 4 = 2
\]

Next, add 4 to both sides:

\[
9y = 6
\]

Now divide by 9:

\[
y = \frac{6}{9} = \frac{2}{3}
\]

Now that we have \( y \), we can substitute it back into the first equation to find \( x \):

\[
x = y - 4 = \frac{2}{3} - 4 = \frac{2}{3} - \frac{12}{3} = -\frac{10}{3}
\]

Now we have the solution \( \left(-\frac{10}{3}, \frac{2}{3}\right) \).

However, it seems there is no exact match from the provided choices. The solution should be simplified or verified against the choices. Let’s calculate the coordinates accurately.

So we can recalculate:

\[
x = y - 4
\]
Substituting \(y = \frac{2}{3}\):

\[
x = \frac{2}{3} - 4 = \frac{2 - 12}{3} = -\frac{10}{3}
\]

Thus, we actually found:
\[
x = -\frac{10}{3}, \quad y = \frac{2}{3}
\]

This simplifies to:

\[
(-3\frac{1}{3}, \frac{2}{3}) \text{ or } (-\frac{10}{3}, \frac{2}{3})
\]

However, since the answer choices provided are:

- no solution
- infinite solutions
- \((-3 \frac{1}{3}, \frac{2}{3})\)
- \((\frac{2}{3}, -3 \frac{1}{3})\)

The closest match based on the options is:\((-3 \frac{1}{3}, \frac{2}{3})\).

Thus the correct answer would be:

**(−3 1/3, 2/3)**.
