  1. Card Sharks To get the first chance to run the cards you must hit your buzzer (your desk) and get the question asked correct. If the answer is incorrect your opponents will have the opportunity to steal. If the answer is still incorrect it will go back to the entire team to steal and continue in that fashion. -Good Luck to all Contestants

  2. Question #1 Find the slope of the line passing through the points (-2, 2)and (1, 3).

  3. Question #2 Find an equation for the line passing through the points (3,-2) and (4,-5). Be able to sketch a graph of the line.

  4. Question #3 Find an equation of the line that passes through the point (-1,5) and has slope of –3. Be able to sketch a graph of the line.

  5. Question #4 Find the slope-intercept form of the line that passes through the point (-3,2) and is perpendicular to 3x+5y=7.

  6. Question #5 Does the equation represent y as a function of x?

  7. Question #6 Evaluate the function at the points x =0, x =2, and x =4.
