1.) Students will make a table of values, illustrate the solution of each problem on a graph, and label the graph. y = 3x - 4; y = x + 3 
2.) Students will solve problems such as the following; they will interpret the solutions in terms of context, address each of the questions, and explain why their results are reasonable: The temperature at 8 a.m. was 3 degrees C. At 10 a.m. it was 7 degrees. If the temperature climbed at a constant rate from 6 a.m. to 12 noon, what was it a 6 a.m.? What was it at 12 noon? 
3.) Students will solve each inequality and graph their solutions on a number line: 
  • y less than or equal to 2; x less than or equal to 0 or x greater than 2;
  • -1 less than or equal to x less than 4
  • -1 less than or equal to x less than 4 
    • 1.) Students will solve problems like the following, showing their work (both computation and graphing), and explain their reasoning:  

    It is the sixth annual cross-country motorcycle race across the Mojave Desert, 70 miles and back. Jason, on a new motorcycle, averages 80 miles per hour going out but has gear trouble and can manage only 60 miles per hour coming back. Eric can go only 70 mph on his motorcycle, but he maintains this speed for the entire race. Who wins the race?  

    Mary's computer needs at least 90 volts of electricity to work. It is damaged, however, if the voltage is 140 volts or more. 

    A. Express the safe voltage range as an inequality  

    B. Graph the inequality in part A. 

    2.) Students will solve each inequality and graph the solution: 

    2y + 4 greater than or equal to 12;  

    y less than or equal to 1
