Answer: -2/5
Step-by-step explanation:
To find the slope, we set the function use y = mx + b forms.
2x + 5y = 10
         5y = -2x + 10              Minus 2x in both side
            y = -2/5x + 10/5       Divide 5 from both side
            y = -2/5x + 2 
In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.
