SOLUTION: The equation for the perpendicular line given that (6, -5) and 9x +8y=7. Here is what I have done so far for the parallel line that I had to figure: y=-9/8x+7/8 slope is -9/

Question 572128: The equation for the perpendicular line given that (6, -5) and 9x +8y=7.
Here is what I have done so far for the parallel line that I had to figure:
y=-9/8x+7/8
slope is -9/8
y-(-5)=-9/8(x-6)
y=-9/8x +7/4
y=8/9x and now I am stuck. sigh.

The equation for the perpendicular line given that (6, -5) and 9x +8y=7.
Here is what I have done so far for the parallel line that I had to figure:
y=-9/8x+7/8
slope is -9/8
----------
Slope of a line perpendicular to the given line must be (8/9)
-----
Form: y = mx + b where m = 8/9 and y = -5 when x = 6
------------------------------------------------
-5 = (8/9)6 + b
-45/9 = 48/9 + b
b = -93/9 = -31/3
-----
Equation:
y = (8/9)x -(31/3)
======================
