Question 945347
Simplify the given line.
{{{highlight_green(11x+2y=10)}}}.
Its slope is {{{-11/2}}}.


The line parallel to it and containing (-10,-15) is
{{{11x+2y=11*(-10)+2(-15)}}}.
Simplify that.


Do you know the needed basic fact to answer the second question?
L for a given line L, p for a line perpendicular to L,
{{{m[L]*m[p]=-1}}}
