Question 1030078
You could solve for y and adjust to general form to read the slope, and then for any line perpendicular, the slope would be the negative reciprocal of that slope.


If you know how STANDARD FORM equation works, the slope of the given line is {{{-2/7}}}, so any line PERPENDICULAR to it will be  {{{highlight(7x-2y=k)}}}, for ANY REAL NUMBER, k.
