Math STAAR Equations and Inequalities

The table shows the distance, y, a cheetah can travel in feet in x seconds. Based on the information in the table, which equation can be used to model the relationship between x and y?

• y = 5x

• y = x + 5

• y = x + 470

• y = 94x

A pilot takes a taxi from the airport to a hotel. The taxi driver charges a $2.50 initial charge plus $2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?

• y = 2.50x + 2.65

• y = 2.65 (x + 2.50)

• y = 2.65x - 2.50

• y = 2.65x + 2.50

Which equation best represents the relationship between x and y in the graph?

• y = 3x + 3

• y = 3x - 1

• y = 1/3x + 3

• y = 1/3x - 1

A store sells new video games for $55 each. Used video games sell for $12 each. Jacob is buying 3 new video games and x used video games. Which equation can be used to find y, the total price Jacob must pay in dollars?

• y = 12x + 55

• y = 12x + 165

• y = 55x + 12

• y = 165x + 12
