1. Find a linear equation whose graph has the indicated slope and passes through the given point.slope 2, point (3,1)

The equation of the line is y=__

(Simplify the answer. Answer expression using x as the variable.)

2. Find the linear equation whose graph passes through the given points. Write the equation in slope-intercept form.

(3,5) and (2,2)

What is an equation of the line? y= __

(Simplify answer. Answer expression using x as the variable. Use integers or fractions for any numbers in the expression.)

3. In a certain year, expenses at a four-year public college averaged $14,900 and were increasing at a rate of $750 per year. Model this information with a linear equation and use the model to predict the average cost of attending a four-year public college.

Let x be the number of years since a certain year and let y be the cost of attending a four-year public college. Choose the equation of a line that models the information.

A.y=750x14,900

B.y=750x+14,900

C.y=750x14,900

Dy=750x+14,900

Part 2

The cost of attending a four-year public college 11 years later is predicted to be $__.

4.In 2011 a country had a population of 122 million and a growth rate of 0.592%. Assuming that this rate remains constant, estimate the population of the country in 2022.

In 2022, the country's population will be about __million.(Round to the nearest hundredth as needed.)

5. A country's populations in 2001 and 2010 are given below. Use this information and the exponential model A=P(1+r)n to find the growth rate for the country over this period.

population(2001)=82 million; population (2010)=114 million

The country's growth rate was approximately __%. (Round to two decimal places as needed.)

6. The number 34.03 is 20.75% of what number?

The number 34.03 is 20.75% of ___. (Answer using an integer or a decimal.)

7. According to a certain central bank from 2000 to 2016 the average price of a new home in a certain region increased by

118% to $554 thousand. What was the average price of a new home in 2000?

The average price of a new home in 2000 was $ __.

(Do not round until the final answer. Then round to the nearest thousand as needed.)
