Find the axis of symmetry for this parabola.
y = 3x2 - 6x - 9
x = -3
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆x = 1
x = 3
x=4
-b/2a=-(-6)/2(3)
=6/6=1
The line to find: y = mx + b
the line perpendicular to y= 2/5x+6/6 so it has the slope m × 2/5 = -1
thus the slope m = -5/2
the line passes through the point (-2,6) so:
6 = (-5/2)×(-2) + b so b = 1
the equation of the line is y = -5/2x +1
