Homework Statement
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.
