You would need to change the slope to -6 because perpendicular lines have opposite reciprocal slopes.
The next number is 38. The pattern is 7, 16, 8, 27, 9; if you look at the first 4 numbers, you notice that it counts to 7, 8, 9. Then you have 16 and 27, if the pattern continues; the next number is 38.
The answer is 9x^3-6x^2+3x
