write an equation for the line perpendicular to y = 3x - 5 that contains (-2,-3).
the relationship of the slopes of perpendicular lines m1 * m2 = -1
In this case m1 = 3, find the slope of the perpendicular line
3m = -1
m =
:
Using the point slope form y - y1 = m(x-x1),
x1=-2; y1=-3; m=
y -(-3) = (x -(-2))
minus a minus is a plus
y + 3 = (x + 2)
y + 3 = x -
y = x - - 3
y = x - -
y = x - is the equation
:
looks like this

note the green intersects at -2,-3
