Question

Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?

Answer 1

y = 1/12x + b

Explanation:

So lines that are perpendicular have a negative reciprocal slope.

If line c has a slope of -12, then line d has a slope of 1/12

So y = 1/12x + b would be perpendicular to c, where b is a constant
