Question 976125

Is the line y=2/3x-11 perpendicular to the line y=-3/26x-11 ? I say no because the slopes are not the same but my college algebra book disagrees with me.
<pre>Are you sure the 2nd equation is: {{{y = - (3/26)x - 11}}}, and not {{{y = - (3/2)x - 11}}}? If the latter, then the book is correct!!
