The winning times for the 200-meter dash can be approximated byf(x)=−0.05783x+147.7, where x is the year. what is the slope of f?

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   , where x is the year.

To find : The slope of f

Solution : Using slope intercept form a linear function is represented as

where, m is the slope and b is the y-intercept.

We can write the function as

Comparing with slope intercept form,

m= -0.05783 and y-intercept = 147.7

Therefore, The slope of f is m= -0.05783.

a)(x-2)^2+(y-1)^2=9
