The problem involves determining the ratio A1/B1 for two equations of lines that are perpendicular, specifically A1x + B1y = C1 and A2x + B2y = C2. The context is rooted in the concept of negative reciprocals in relation to the slopes of perpendicular lines.
The discussion includes differing opinions on the correctness of the initial approach to expressing A1/B1. Some participants affirm the reasoning, while others express confusion or disagreement, indicating an ongoing exploration of the concepts involved.
Participants reference the context of homework constraints and express frustration with the grading system, suggesting that there may be additional pressures influencing their interpretations.

If the graphs of A1x + B1y = C1 and A2x + B2y = C2 are perpendicular, express the following in terms of A2 and B2.
A1/B1= ?
Homework Equations
Negative reciprocal
The Attempt at a Solution
I thought that by expressing A2 and B2 with A1/B1, it would just be the negative reciprocal if its perpendicular so it would be -B2/A2 which is incorrect.
