Answer:
The slope of f is m= -0.05783.
Step-by-step explanation:
Given : The winning times for the 200-meter dash can be approximated by [tex]f(x)=-0.05783x+147.7[/tex] , where x is the year.
To find : The slope of f
Solution : Using slope intercept form a linear function is represented as
[tex]y=mx+b[/tex]
where, m is the slope and b is the y-intercept.
We can write the function as [tex]y=-0.05783x+147.7[/tex]
Comparing with slope intercept form,
m= -0.05783 and y-intercept = 147.7
Therefore, The slope of f is m= -0.05783.
