The slope of the line passing through the points (4, -2) and (-5, 4) is slope = [4 - (-2)]/(- 5 - 4) = 6/-9 = -2/3

x + 2x/x + 1
= x + 2 + 1
= x + 3

x + 2/3 + 2x - 4/4 = 3;
x + 2/3 + 2x - 1 = 3;
3x - 1/3 = 3;
3x = 3 + 1/3;
3x = 10/3;
x = (10/3)/3;
x = 10/9

(16x^2 -25) ÷ (4x + 5)
= (16x^2/4x+5) - (25/4x+5)
= 4x - 5

(6x^3 + 11x^2 - 4x - 4)/(3x - 2)
= (6x^3/3x - 2) + (11x^2/3x - 2) - (4x/3x - 2) - (4/3x - 2)
= 2x^2 + 5x + 2

(27x^4 - 18x^3 + 9x^2) ÷ 3x
= (27x^4/3x) - (18x^3/3x) + (9x^2/3x)
= 9x^3 - 6x^2 + 3x

(12x^3 - 11x^2 + 22x - 5) ÷ (4x - 1)
= (12x^3/4x - 1) - (11x^2/4x - 1) + (22x/4x - 1) - (5/4x - 1)
= 3x^2 - 2x + 5
