Answer:
y = - 2x + 8
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 9 ← is in slope- intercept form
with slope m =

given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute the point (3, 2 ) into the partial equation
2 = - 2(3) + c = - 6 + c ( add 6 to both sides )
8 = c
y = - 2x + 8 ← equation of perpendicular line
