Question

Lines a and b are perpendicular. The equation of line a is =13+3 y = 1 3 x + 3 . What is the equation of line b ?

Answer 1

See below

Explanation:

Perpendicular lines have slopes which are negative reciprocals. Line a with the equation y = 13x + 3 has slope 13. This means Line b which is perpendicular will have slope -1/13.

The equation of line b is any equation where -1/13 is the slope/

Example: y = -1/13x + 5 or y = -1/13x - 6
