<span>-7x + 8y = -9
         8y = 7x - 9
           y = 7/8x - 9/8 

so line </span><span>-7x+8y=-9 has slope = 7/8

</span><span>perpendicular lines, slope will be opposite and reciprocal
so new line has slope = -8/7

passing thru </span><span>(2,-5) 
</span>y = mx + b
-5 = -8/7(2) + b
-5 = -16/7 + b
b = -5 + 16/7
b = -35/7 + 16/7
b = -19/7

equation
y = -8/7x - 19/7
