A line has the equation [tex]6x - 7y = -11[/tex]. What is the equation of a parallel line going through the point [tex](-6, -5)[/tex]?

The equation is given by [tex]Ax + By = C[/tex], where
[tex]\[ A = \ \ \ \ \ B = \ \ \ \ \ \text{and} \ C = \ \ \ \ \][/tex]

To find the equation of the line that is parallel to the given line [tex]\(6x - 7y = -11\)[/tex] and passes through the point [tex]\((-6, -5)\)[/tex], we'll follow these steps:

1. Identify the coefficients [tex]\(A\)[/tex] and [tex]\(B\)[/tex] from the given equation of the line:
- The standard form of the line equation is [tex]\(Ax + By = C\)[/tex].
- For the given line [tex]\(6x - 7y = -11\)[/tex], we can see that:
- [tex]\(A = 6\)[/tex]
- [tex]\(B = -7\)[/tex]

2. Determine the equation of the parallel line:
- Parallel lines have the same coefficients for [tex]\(x\)[/tex] and [tex]\(y\)[/tex], meaning they have the same [tex]\(A\)[/tex] and [tex]\(B\)[/tex] values.
- Therefore, the parallel line will also have [tex]\(A = 6\)[/tex] and [tex]\(B = -7\)[/tex].

3. Find the constant term [tex]\(C\)[/tex] for the new line:
- The new line must pass through the point [tex]\((-6, -5)\)[/tex].
- Substitute [tex]\(x = -6\)[/tex] and [tex]\(y = -5\)[/tex] into the equation [tex]\(6x - 7y = C\)[/tex] to find [tex]\(C\)[/tex]:

[tex]\[ 6(-6) - 7(-5) = C \][/tex]

Now, calculate the expression:

[tex]\[ 6 \cdot (-6) + (-7) \cdot (-5) = C \][/tex]
[tex]\[ -36 + 35 = C \][/tex]
[tex]\[ -1 = C \][/tex]

4. Write the final equation of the parallel line:
- Thus, the equation of the parallel line passing through [tex]\((-6, -5)\)[/tex] is given by:

[tex]\[ 6x - 7y = -1 \][/tex]

Therefore, the values are:
[tex]\[ A = 6, \quad B = -7, \quad C = -1 \][/tex]

So, the equation of the parallel line is:
[tex]\[ 6x - 7y = -1 \][/tex]
