Respuesta :

The equation of the line perpendicular ton the given line is y = -3x +6

what is the equation of a straight line ?

A equation of a straight line is given by

y = mx+c ,

where m is the slope and c is the intercept on y axis.

The given line is

y = (1/3)x +4

The slope is 1/3

Te slope of the line perpendicular to a line is given by

m * m' = -1

(1/3) * m' = -1

m' = -3

The equation of the line is

y = -3x + c

The  x intercept is 2

At y = 0, x =2

0 = -6 +c

c =6

Therefore the equation of the line perpendicular ton the given line is

y = -3x +6
