The equation of line CD is y=3x-3. Write an equation of a line perpendicular to line CD in slop-intercept form that contains point (3,1)

Respuesta :

y = -x/3 + b1 = -3/3 + b              
 substitute values of point1 = -1 + b                  
then reduce2 = b                          
 add one to both sides y = -x/3 + 2
