Question

Which equation represents the line that is perpendicular to y=1/6 & passes through (-8,-2)?

a) y = -6
b) y = -8
c) x = -8
d) x = -2

Answer 1

x = -8

Explanation:

slope of y = 1/6 is zero

the negative reciprocal of zero is considered to be 'undefined', which is the slope of x=-8 (or x = 'any number')
