The table shows the amount of milk that Wisconsin dairy farms produced from 1940 to 1997. Use a linear model to estimate milk production in 1990.

To estimate milk production in 1990 using a linear model, we can use the data points provided for 1940, 1972, and 1997.

Let's assign the x-axis as the years and the y-axis as the milk produced.

1940: x1 = 1940, y1 = 7
1972: x2 = 1972, y2 = 7
1997: x3 = 1997, y3 = 8

We can now use the point-slope formula to find the equation of the line:

(y - y1) = m(x - x1)

First, let's find the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

m = (7 - 7) / (1972 - 1940)
m = 0 / 32
m = 0

Since the slope is 0, the equation of the line will be a constant value of y = 7. Therefore, the estimated milk production in 1990 will be 7 billion lbs.

Our final answer is:

Estimated milk production in 1990: 7 billion lbs.
