Question

Find the slope of a parallel line and the slope of a perpendicular line.
y=12x-1​

Answer 1

Explanation:

12x - y = 1

slope of m1 = - coefficient of x / coefficient of y

= - 12 / -1

= 12

# when it is parallel;

m1 = m2

12 = m2

# when it is perpendicular;

m1 * m2 = -1

12 * m2 = -1

m2 = -1 / 12
