Students receive full credit for only selecting these two choices: C. = 1, = -1 and F. = 0, = 0 x y x y No Solution Exactly 1 Infinitely Many Solution Solutions There is one solution. (Or any answer that expresses the same idea.) NOTE: There is a variety of possible explanations, such as know when then for both “I the slopes are different, the lines will graph of the equations,” “because intersect,” “the lines are not parallel so they will cross,” etc. Infinitely many solutions. (Or any answer that expresses the same idea.) The graph will be a line. Student circles the intersection points as shown. There are two solutions. There is a variety of possible explanations, including the graphs intersect at two “because equations share two are two points on the graph of both points,” “the values,” “there equations,” etc. 8,400 tickets were sold at the music festival; 11,600 tickets were sold before the music festival There is one solution. There is a variety of possible explanations, including the lines will eventually “because lines are not lines have etc. cross,” “the parallel,” “the different slopes,” 9. (3.5, or any equivalent answer. –3.5) 10. Student only selects these three statements: (-3, 2) is a solution to equation 1. □
