The coordinate grid shows the plot of four equations: A coordinate grid is shown from negative 12 to positive 12 on the x axis and also on the y axis. Line A passes through the ordered pairs negative 3, 4 and 9, negative 2. Line B passes through the ordered pairs 2, 8 and 8, negative 8. Line C passes through the ordered pairs negative 3, negative 4 and 4, 6. Line D passes through the points 2, negative 2 and 5 and 6. Which set of equations has (3, 5) as its solution? A and D C and D A and C B and C Question 18(Multiple Choice Worth 1 points) (08.05 HC) The work of a student to solve a set of equations is shown: Equation A: y = 16 – 2z Equation B: 7y = 2 – 4z Step 1: –7(y) = –7(16 – 2z) [Equation A is multiplied by –7.] 7y = 2 – 4z [Equation B] Step 2: –7y = 16 – 2z [Equation A in Step 1 is simplified.] 7y = 2 – 4z [Equation B] Step 3: 0 = 18 – 6z [Equations in Step 2 are added.] Step 4: 6z = 18 Step 5: z = 3 In which step did the student first make an error? Step 3 Step 4 Step 1 Step 2 Question 19(Multiple Choice Worth 1 points) (08.01 MC) Lines C and D are represented by the equations given below: Line C: y = x + 8 Line D: y = 3x + 2 Which of these shows the solution to the system of equations and explains why? (3, 11), because the point does not lie on any axis (3, 11), because both lines pass through this point (4, 14), because one of the lines passes through this point (4, 14), because the point lies between the two axes You must check the box below prior to submitting your exam!
