1.02 Graded Assignment: Slope and Y-Intercept sum consumer math

Complete the problems. For each problem do each of the following:
• Find the ordered pairs, using the x-values and equation given.
• Make a T-table with the ordered pairs, like the ones in the quick practice above.
• Use appropriate values for the x-axis and y-axis, label each axis (see graphs above).
• Graph the points.
• Draw a line through the points to represent the graph of the equation.

1. John began his job making $25 the first day. After that he was paid $6.75 per hour. The equation is y = 6.75x + 25. Use x-values: 0, 20, and 40.

2. A membership to Movie Night Movie Club costs $10, plus $2 per movie. The equation is y = 2x +10. Use x-values: 0, 5, and 10.

3. you are using 0.05 gallons per mile of a SUV gas tank that holds 16 gallons. The equation is y=-0.05x+16. They are the same equation. Use x-values: 0, 160, and 320.

4. The temperature was 56 degrees this morning, but dropped one degree per hour through the rest of the day. The equation is y=-x+56. They are the same equation. Use x-values: 0, 5, and 10.

5. Your weight-lifting class cost you a $20 fee up front, and $5.50 per class. The equation is y = 5.50x + 20. Use x-values: 0, 10, and 20.
