Solve the problem. Express your answer as an integer or simplified fraction. -

Use the REGRESSION feature on a graphing calculator. -The use of bottled water in the United States has shown a steady increase in recent years. The table shows the annual per capita consumption for the years 1995 - 2001. With x being the years since 1995, find the linear function that represents this data. Round your answer to two decimal Places.

Provide an appropriate response. -Find the standard form of the equation of the line with slope of and passing through (4, 4).

Provide an appropriate response. -Write the equation of a line that passes through (3, 9) and (0, -7). Write the final answer in the form Ax + By = C where A, B, and C are integers with no common divisors (other than ±1) and A > 0.

Solve the inequality and graph. Express your answer in interval notation. -7x - 3 > 6x - 6

Write an equation of the line with the indicated slope and y intercept. -Slope = 4, y intercept = -5

Provide an appropriate response. -Find the line passing through the two points. Write the equation in standard form. (10, 9) and (10, 1)

Find the slope of the line containing the given points. -(6, 1) and (6, - 4)

Solve the problem. -At a local grocery store the demand for ground beef is approximately 50 pounds per week when the price per pound is $4, but is only 40 pounds per week when the price rises to $5.50 per pound. Assuming a linear Relationship between the demand x and the price per pound p, express the price as a function of demand. Use This model to predict the demand if the price rises to $5.80 per pound.
