Step-by-step 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
