A part of a linear function is shown on the grid. What is the range of the part of the linear function shown? Choose the correct answer from each drop-down menu to complete the sentence. The range is the set of all real numbers [_____] and [_____].

The domain and range of part of linear function r are given as x > 5 and y < 2. Which graph could represent this part of linear function r?

• Graph a

• Graph b

• Graph c

• Graph d

The table represents some points on the graph of a linear function. Which function represents this relationship?

• y = -3/2x + 4

• y = -3/2x - 14

• y = -2/3x - 9

• y = -3/2x - 1

Printer ink costs $18.99 per cartridge. The company that sells the ink cartridges charges a flat rate shipping fee of $7.95, no matter the number of cartridges purchased in a single order. Which linear function models the total cost, t, for a single order of c cartridges?

• t = 26.94c

• t = 18.99c + 7.95

• t = 26.94c

• t = 18.99c + 7.95

The graph shows point P and line m. Which equation best represents the slope-intercept form of the line that passes through point P and is parallel to line m?

• y = 2/3x - 5

• y = -2/3x + 2/3

• y = 2/3x + 5

• y = -2/3x - 2/3

A line is graphed on a coordinate grid. Refer to the diagram provided. Which statement about the line is true?

• The equation of the line is x = -4, and the slope is undefined.

• The equation of the line is y = -4, and the slope is equal to -4.

• The equation of the line is x = -4, and the slope is equal to -4.

• The equation of the line is y = -4, and the slope is undefined.

A customer is ordering hats and T-shirts from an online store. Each hat costs $7, and each T-shirt costs $10. The customer receives free shipping if the amount of the order is over $100. Write an inequality that represents all possible combinations of hats, x, and T-shirts, y, in an order that qualifies for free shipping.

The tables of ordered pairs represent some points on the graphs of two different lines, Line a and Line b. Which system of equations represents the graph of these two lines?

• x - 6y = -90, x - 3y = 27

• x + 6y = 90, x + 3y = -27

• 6x - y = -15, 3x - y = 9

• 6x + y = 15, 3x + y = -9
