Question 906673


through ({{{0}}},{{{-8}}}) and perpendicular to {{{20x+4y=41}}}

{{{4y=-20x+41}}}

{{{y=-20x/4+41/4}}}

{{{y= -5x+10.25}}}

*[invoke equation_parallel_or_perpendicular "perpendicular", -5, 10.25, 0, -8]


better graph:


{{{ graph( 600, 600, -15, 15, -15, 15, -5x+10.25, (1/5)x-8) }}}
