Math Question?

Create a scatter plot using the data relating “years since 1900” and “world record time” for the men’s 100 meter dash. Then write an equation for a linear model representing the data. Define the variables you use in your equation.

I keep getting the answer wrong so I’m not sure what I’m doing wrong, thanks!

    x=0 for year 1912 , y=10.6

    x=9 , y=10.4

    x=18 , y = 10.3


    x=96 , y=0.7

    x=97 , y=9.6

    input data to calculator for a scatter plot and a linear regression line


    y=10.477 - 0.00871 x , x=number of year after 1912
