(need ! )which of the following lines is perpendicular to y= 3x + 2?

a. y=3x -1/2

b. y=-1/3x+6

c. y=1/3x+2

d. y=3x+1/2

Step-by-step explanation:

We have to find the equation of the line from the options given which is perpendicular to the line y=3x+2.

In order to do so we must know that , the product of the slope of the two perpendicular lines is always -1

Hence

if the slope of line A is "m" and the line B which is perpendicular to A, will have

Also , in the slope intercept form of any equation the coefficient of x is our slope. Hence the slope of y=3x+2., is 3

Hence the slope of any line perpendicular to this will be

as the product of two slopes is -1

Hence in the given options only c options has the line whose slope is  

the least common denominator is 40
