Imagine the graph for the relation 4x-5y+20 = 0.
What would be its slope?

Sagot :

4x - 5y + 20 = 0
             - 20  - 20
        4x - 5y = -20
 4x - 4x - 5y = -20 - 4x
              -5y = -20 - 4x
              -5y = -4x - 20
               -5         -5
                 y = ⁴/₅x + 4
The slope would be ⁴/₅.
