Find an equation for the line perpendicular to the line
equation of the perpendicular line:
if given that the line perpendicular to the line , means they will have slopes negative reciprocal to each other
so, first find a slope of given line:
=> slope is
and its negative reciprocal will be a slope of the perpendicular line:
if , than negative reciprocal is =>
now we have a slope, and your equation is so far
since given that perpendicular line having the same y-intercept as , we need to find that y-intercept
=> y-intercept is at
so, your equation is:
