Question 1155051
.
What is the slope of a line perpendicular to the line whose equation is 12x-9y=135 fully reduce your answer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



<pre>
The given line equation is

    12x - 9y = 135.


Write it in the slope-intercept form

    y = {{{(12/9)x}}} - {{{135/9}}},

or

    y = {{{(4/3)x}}} - 15.


Coefficient at 'x' is  {{{(4/3)}}},  so the slope of the given line is {{{4/3}}}.


The slope of a line perpendicular to this line is opposite reciprocal to  {{{4/3}}},  i.e. is  {{{-3/4}}}.


<U>ANSWER</U>.  The slope of a line perpendicular to the given line is  {{{-3/4}}}.
</pre>

Solved correctly.

The "solution" in the post by @mananth is absurdist and incorrect, both FATALLY and TOTALLY.
