Let line 1 be the graph of 5x+8y=-9. Line 2 is perpendicular to line 1 and passes through the point (10,-10). If line 2 is the graph of the equation y=mx+b, then find m+b.

5x+8y=-9.

y = -5/8 x  - 9/8      slope = -5/8    perpindicular = 8/5

 

y = 8/5 x  + b    sub in given point

-10 = 8/5 (10) + b   shows b =  -26

 

y = 8/5 x -26

 

You can finish >...........
