Find the equation of the line passing through point A and perpendicular to AB

y = m x + b       equation of straight line

When x = 0 then y = 6     (from graph)

y = m x + 6

When y = 0  then x = 3  and m = -2

y = - 2 x + 6    is the equation of the line

m m' = -1      for perpendicular lines   (gradient =  1 / 2)

y =  x / 2 + 6     for a perpendicular line   (if x = 0 then y = 6)

nope

step-by-step explanation:

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
