We can look at the graph
we are given equation as
[tex] y=4.25x [/tex]
we know that
this is equation of line
it means that it will have constant slope
rate of change of first individual will be slope of the line
[tex] =4.25 [/tex]
rate of change of second individual will be slope of the line
[tex] =4.25 [/tex]
so, the difference between them will be
[tex] =4.25-4.25
[/tex]
[tex] =0 [/tex]..............Answer
