y=mx+b
m=slope
perpendicular lines have slopes tha tmultily to -1
y=4x-3
slope=4
perpendiuclar is
4 times what=-1?
-1/4
y=-1/4x+b
sub that opint
(8,2)
x=8
y=2
2=-1/4(8)+b
2=-2+b
add 2
4=b
y=-1/4x+4 is answer

I wrote the equation y=4x-30. I attached an image of a graph that has the original line (in blue) the point you gave (red dot), and my line (in green) for you to see.
