Скачать или смотреть Digital SAT Math – Geometry (Hard) | Perpendicular Line Slope Rule | ID: db422e7f

This problem tests your understanding of perpendicular lines and their slopes.
Remember — when two lines are perpendicular, their slopes multiply to –1.
By isolating y from the standard form equation, you can quickly find the slope and then its perpendicular pair.

[Study Tip]
🟩 Quick Tip:
When you see the word “perpendicular”, immediately think negative reciprocal slope.
👉 Example: if the slope is -2, the perpendicular slope is 1/2.
