Write the equation of the line perpendicular to y= 2/5x+6/6 that passes through the point (-2,6)

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

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3

If i could just have the statements, i'd be able to
