On a map of downtown lineville, 12th street is perpendicular to avenue j. the equation y = -4x + 3 represents 12th street. what is the equation of avenue j if it passes through the point (8, 16)?

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
