JORDAN KOVALSKY Math - 112 Spring 2010 WeBWorK Assignment Lesson 06 - Graphs of Equations Due Date: 09/20/2010 at 11:59pm CDT. The primary purpose of WeBWorK is to let you know that you are getting the correct answer or to alert you if you are making some kind of mistake. You can use the Feedback button on each problem page to send e-mail to the course instructors. 1. (1 pt) Does the point ( 2 , 2 ) lie on the graph of the equation 3 x 2 + 3 y 2 = 24? ? Correct Answers: y 2. (1 pt) Does the point ( 2 , 2 ) lie on the graph of the equation 4 x 2 + 6 y 2 = 44? ? Correct Answers: n 3. (1 pt) Does the point ( a 2 , a + 3 ) lie on the graph of the equation y = x + 8? ? Correct Answers: n 4. (1 pt) Solve the equation 6 x + 4 y = 8 for y (in terms of x ). y = Fill in the following values: x = 4 y = x = 2 y = x = 0 y = x = 2 y = x = 4 y = Correct Answers: -6 * x / 4 + 8 / 4 -6 * (-4) / 4 + 8 / 4 -6 * (-2) / 4 + 8 / 4 -6 * 0/ 4 + 8 / 4 -6 * 2 / 4 + 8 / 4 -6 * 4 / 4 + 8 / 4 5. (1 pt) The graph of the equation 3 x 4 y = 12 is a straight line. Graph the line and indicate the its x -intercept and y -intercept on your graph. This problem needs to be handed in on paper to your instructor. Download the .pdf ±le associated to this assignment (in Moo- dle), print it out, and submit your answer on it. Note: The score for this problem will be adjusted later; you do not need to submit an answer on this problem. 6. (1 pt) The graph of the equation x = 2 y 4is a straight line. Graph the line and indicate the its x -intercept and y -intercept on your graph.
