The graph of a linear function is shown on the grid. (Note: There should be arrows.) Which equation is best represented by this graph?

• y-2=4(x-1)

• y-6=-4(x-2)

• y-3=-4(x-10)

• y+7=4(x+3)

Rick prepares 7 kilograms of dough every hour he works at the bakery. The baker from the previous shift left 50 kilograms of dough in the refrigerator. Write an equation that models how much dough Rick has after x hours of work.

• d(x)=50-7x

• d(x)=50+7x

• d(x)=7(x+50)

• d(x)= -7(x+50)

The graph shown represents the number of tickets that a theater must sell in order to generate $350 in revenue from ticket sales. What statement best describes the x-intercept?

• If the theater only sells children tickets, they must sell 140 in order to generate $350 in revenue.

• The theater could sell 30 adult tickets and 80 children’s tickets to generate $350 in revenue.

• If the theater only sells adult tickets, they must sell 70 in order to generate $350 in revenue

• One adult ticket is twice as much as one children ticket.
