Question 674787
The slope of y = {{{(-2/7)x-5}}}
is  {{{-2/7}}}
...
A perpendicular line will have a slope of negative inverse, which is {{{7/2}}}
...
Using (2, 4)
y - 4 = {{{(7/2)(x-2)}}}
y - 4 = {{{(7/2)x - (7/2)(2)}}}
y - 4 = {{{(7/2)x - 7}}}

y = {{{(7/2)x- 7 + 4}}}
{{{highlight_green(y = (7/2)x-3)}}}
...
{{{graph(300,200,-10,10,-10,10,(-2/7)x-5,(7/2)x-3)}}}
