I have tried to answer this and I can tell by looking at what I did that I am no where near correct. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Write the slope-intercept equation for the line that passes through (-2,3) and is perpendicular to 2x – 9y = -12
-----------
Find the slope of the line.
Solve for y:
2x – 9y = -12
9y = 2x + 12
y = (2/9)x + 4/3
-----
The slope of the line is 2/9
The slope of lines perpendicular is the negative inverse, = -9/2
-----
Use y = mx + b and the point to find b, the y-intercept
3 = (-9/2)*(-2) + b
b = -6
-----
--> y = (-9/2)x - 6
