2. Consider the selection of linear equations presented below: Equation A: 6y + 10:1: = 3 Equation B: y = 4:1: 10 Equation C: 2y 32: + 5 = 0 Equation D: 51:; = 8:c 12 Equation E: 2y = 72: + 3 Equation P: y = gs: + 4 Which of these equations (if any) have a negative slope? (4 marks all correct, 0 marks otherwise) 3. Suppose that a straight line passes through the points (-5, 3) and (-2, 8) in the Cartesian plane. (a) Find the intercept and slope of this straight line, and write out the full equation for the straight line. (5 marks) Note that this question is similar to the type of question you may encounter in the oniine numeracy quizzes. However, here you must make sure to include at! your working. b Suppose that you are given a third point 6, 21 . Does this point lie on the strai ht line ou obtained in g y part 2a? Make sure to show your working to support your conclusion. ( 3 marks)
