Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Lets convert two of these results into coordinates:
10, 2
20, 4
To calculate rate of change, the equation is:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Where x1 and y1 are the first set of coordinates and x2 and y2 are the second set. Plug the values in:
[tex]\frac{4 - 2}{20 - 10}[/tex]
[tex]\frac{2}{10}[/tex]
Which simplifies to:
[tex]\frac{1}{5}[/tex]
Hope this helps!
