• 5x - 2y = -34

• 5x - 2y = -28

• 5x - 2y = -4

• 5x - 2y = 8

Question 3

The table represents some points on the graph of a linear function. 

 Which equation represents the same relationship?

Select two correct answers.

Question 5

Two points are plotted on the grid.

Which equation in slope-intercept form best represents the line that passes through these two points?

• y = x - 4

• y = -2x + 1

• y = x - 2

• y = -4x + 1

Question 6

The total cost, y, for x tickets to a concert includes a flat fee for processing and a cost per ticket.  One customer purchased 3 tickets for a total cost of $100.  Another customer purchased 9 tickets for a total cost of $400.  

Write a linear equation in slope-intercept form that represents the total cost in dollars, y, for x tickets.

• y = 33x - 49

• y = -50x + 50

• y = 50x - 50

• y = 46x - 4997
