100 Write the equation in slope-intercept form. Then, identify the slope and y -intercept. 5 y – 3 x = 12

200 Write the equation in slopeintercept form. Then, identify the slope and y-intercept. -6 x – 4 y = 8

300 A family of squirrels takes up residence in the roof of your house. You call a company to get rid of the squirrels. The company traps the squirrels and then releases them in a wooded area. The company charges C = 30 + 15 s where C is the total cost and s is the number of squirrels. Graph the equation. Identify the domain and range.

400 A family of squirrels takes up residence in the roof of your house. You call a company to get rid of the squirrels. The company traps the squirrels and then releases them in a wooded area. The company charges C = 30 + 15 s where C is the total cost and s is the number of squirrels. What do the slope and y-intercept mean?

500 A new toilet model has two different flush settings in order to conserve water. One setting uses 1. 6 gallons of water per flush and the other setting uses 0. 8 gallons of water per flush. The total amount w (in gallons) of water used in the first setting is given by the equation w = 1. 6 f where f is the number of times the toilet is flushed. The total amount of water used in the second setting is given by the equation w = 0. 8 f. Graph both equation in the same coordinate plane. What do the slopes and the w-intercepts mean in this situation?

100 Is 3 y – 2 x = 6 x an example of direct variation? If it is, why and what is the constant of variation?

200 Is xy + 4 = 0 an example of direct variation? If it is, why and what is the constant of variation?

300 Y varies directly with x. If x is 1/5 when y is -1, what is x when y is 8?

400 Y varies directly with x. If x is 3/4 when y is 2, what is y when x is 9?

500 X varies directly with y. If x is 8 when y is -3, what is x when y is -4?

100 Evaluate the function f(x) = 8. 5 – 10 x when x = -3.

200 Find the value of x so that f(x) = -39. 6 for the function f(x) = 10 x – 8. 1

300 How does the function g(x) = x + 4 differ from the parent function f(x) = x?

400 How does the function g(x) = 4 x differ from the parent function f(x) = x?

500 You join a gym that charges a $75 initial sign up fee and $35 a month for a membership. The total cost of the membership can be modeled by f(x) = 35 x +75 where x is the number of months of the membership. After some time, you decide to rent a locker that costs $50 for the entire year. A function for the total cost of the membership with the locker rental is g(x) = 35 x +125. Graph both functions. How is the graph of g(x) related to the graph of f(x)?
