Linear Functions Quiz A.2C

Which function best represents the relationship shown in the graph?

The total cost, y, for x tickets to a concert includes a flat fee for processing and a cost per ticket. One customer purchased 4 tickets for a total cost of $160. Another customer purchased 8 tickets for a total cost of $300. Which linear equation represents the total cost in dollars, y, for x tickets?

• y = 40x

• y = 37.5x

• y = 35x + 20

• y = 20x + 35

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 = -3/2x - 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?

• c = 2694t

• c = 1899c + 795

• t = 2694c

• t = 18.99c + 7.95

The graph of a linear function is shown on the grid. Which equation is best represented by this graph?

The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship. Which equation best represents this situation?

Which function is best represented by the graph?

• ( g(x) = 6x + 4 \)

Which function represents \( f \) based on the table of values?

• ( f(x) = 26(x - 2)

• f(x) = -26(2x - 1)

• f(x) = 13(x - 2)

• f(x) = -2.2(26x - 1)

Which equation is best represented by the graph?

Based on the table, which function models this situation?

• f(n) = -3n + 24

• f(n) = -3n + 64
