I am confused on this one. The Chen family bought a small business. The equation ý = 4.2x -
12.9 models the business's cash value, in thousands of dollars, x years after they bought the business.

Which statement best explains what the y-intercept of the equation means?

• The business lost $12,900 every year after the Chen family bought it.

O The Chen family paid $12,900 for the business.

After the Chen family bought the business, the business lost $12,900 in 4.2 months.

O The business was $12,900 in debt when the Chen family bought it.

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
