Math Problem Statement
Solution
To solve this problem, we need to find an equation of a line that is parallel to and passes through the point .
Step-by-Step Solution:
-
Identify the slope of the given line: The slope-intercept form of a line is , where is the slope and is the y-intercept. From the given equation , the slope is 5.
-
Use the fact that parallel lines have the same slope: Since we are looking for a line that is parallel to , the slope of the new line must also be .
-
Substitute the slope into the slope-intercept form: We now have the equation in the form . The only unknown left is the y-intercept .
-
Use the point (-6, -1) to solve for :
- Substitute and into the equation:
-
Write the equation of the line: Now that we have , the equation of the line is:
Conclusion:
The correct answer is C. .
