Write the slopeintercept equation for the line that passes through (2, 3) and is perpendicular to 2x – 9y = 12

easiest way:
since the 2 lines must be perpendicular, the new equation must look like
9x + 2y = c
Plug in (2,3)
18 + 6 = c
c = 12
equation is : 9x + 2y = 12
in slopeintercept form:
2y = 9x  12
y = (9/2)x  6
