Write an equation that models the line of best fit for the relationship between rainfall and umbrellas sold. (round all values to the nearest hundredth)

• g(x) is translated 3.4 units right and 6 units down

• g(x) is translated 3.4 units right and 6 units up

• g(x) is translated 3.4 units left and 6 units down

• g(x) is translated 3.4 units left and 6 units up

WHich set of ordered pairs DOES represent a function?

• { (0,3), (3,0), (1,4), (4,1) (1,2) }

• { (1,1), (2,2), (3,3), (4,4), (5,5)}

The table shows how Beth’s total earnings at her part-time job are related to the number of weeks she has worked. Which linear function could model Beth’s total earnings as a function, f(x), of the number of weeks she worked, x?

hint: you can find the slope and y-intercept OR you can use desmos to make the line of best fit.

• f(x) = 200x + 400

• f(x) = 200x + 800

• f(x) = 200x

• f(x) = 200x + 200
