2x + 12y = -1 12y = -2x - 1 y = - 1/6x - 1/12...slope here is -1/6. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular line will need a slope of 6.
y = mx + b slope(m) = 6 (0,9)...x = 0 and y = 9 sub and find b, the y int 9 = 6(0) + b 9 = b
