easy peasy
perpenduclar lines have slopes taht mulitply to get -1
y=mx+b
m=slope
12th street is y=-4x+3
slope is -4
-4 times what=-1
answer is 1/4
the slope of other line is y=1/4x+b
if it passes through (8,16) then
find b
(8,16)
(x,y)
sub 8 for x and 16 for y ad find b
16=1/4(8)+b
16=2+b
14=b
the equation of ave J is y=1/4x+14
