The answer is -14 . i think
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
LN=8 because every time there is a midpoint you have to divide it in half. So 64,32,16,8
-3...idk what your asking...but on a number line, 3 places to the left of zero is negative three
