Which of the following is an equation of a line perpendicular to the equation
y = 3x + 1?

choice C

Step-by-step explanation:

i used process of elimination- the slope of a perpendicular lines is the original slopes opposite and reciprocal

so the slope becomes -1/3

since 3's reciprocal is 1/3

and the opposite of that is -1/3

the only answer choice with that slope is c

(23*2)-12=x     x=34
