Question 475578


*[invoke slope 9, 6, 1, 4]

the slope perpendicular to it is {{{m=-1(1/4)=-4}}}


now we can find the Equation of a line that passes through M (9,6) and N(1,4)

*[invoke calculating_slope 9, 6, 1, 4]

{{{y=(1/4)x+15/4}}}

so, the line perpendicular to it is {{{y=-4x+15/4}}}

{{{ graph( 500, 500, -10, 10, -10, 10, (1/4)x+15/4, -4x+15/4) }}}
