Question # 3: 30 Seconds During a 4 hour drive, a truck driver traveled at a rate of 60 miles per hour for the first hour and 75 miles per hour for the following 3 hours. Which is the average rate the truck driver traveled during these 4 hours? Answer: about 71.25 miles per hour
Question # 10: 1 minute Find the slope of the line that passes through the points (5, 2) and (5, -2). Answer: undefined.
Question # 11: 30 sec Find the slope of the line that passes through the points (0,6) and (5, -4). Is your slope positive or negative? Answer: -2 (negative)
Question # 12: 1 minute Find the slope of the line that passes through the points (0,4) and (-3,4). Answer: 0
Question # 14: 1 min What is the rate of change in the context of this situation?
Question # 15: 30 sec What is the slope and y intercept of the graph of the equation 4y = 6x +12? Answer: m = 3/2; b = 3
Question # 16: 1 minute What is the slope and y-intercept of the following equation? 8x - 4y = -12 Answer: Slope = 2, y-intercept (0, 3)
Question # 17: 1 minute Suzie was give two pieces of information and has to write the equation of a line. She knows the line crosses the y-axis at (0, -3) and has a slope of 5. What is the equation of the line? Answer: y = 5x – 3
Question # 20: 1 minute Below the graph y = -3/4x + 3 is shown. What is the y value in this function when x = -4 Answer: y = 6
Question # 21: 1 minute Write an equation in slope intercept form of the line that passes through the point (-3, -1) and has a slope of 4. Answer: y = 4x + 11
Bonus Question! 1 min. Christmas Riddle! If athletes get athletes foot, what do astronauts get?? Answer: missletoe!
ANSWER Notice that the statement 2x + 10 = 2x + 10 is true for all values of x. So, the equation is an identity, and the solution is all real numbers. Question # 10: 2 min. Solve the equation, if possible.
