Question 836716
contains the point (4,1) and that is perpendicular to the line y=3x+5


"perpendicular", and having your given equation already in slope-intercept form, the slope for the perpendicular line is {{{-(1/3)}}}, because you must have {{{(3)*m=-1}}}, where m is slope.


Your desired equation to find is {{{highlight_green(y=-(1/3)x+b)}}}, and you substitute the given point coordinates to find the value of b.
