Remember, y=mx+b, where m=slope. So all you need to do is solve for y.
.
5y=160%2B9x
Divide by 5: y=32%2B%289%2F5%29x
So y=%289%2F5%29x%2B32, and therefore m=9%2F5
.
also 5x=90-9y
Add 9y to each side: 5x%2B9y=90
Subtract 5x from each side: 9y=-5x%2B90
Divide by 9: y=%28-5%2F9%29x%2B10
Therefore, m=-5%2F9
