1.a system of two linear equations is graphed on a coordinate plane. if the system of equations has infinitely many solutions, which statement must be true? a. on the graph, there is exactly one point (x, y) that satisfies both equations. b. on the graph, any point (x, y) that satisfies one of the equations cannot satisfy the other equation. c. on the graph, there are no points (x, y) that satisfy both equations. d. on the graph, any point (x, y) that satisfies one of the equations must also satisfy the other equation. 2.mark drank a total of 10 glasses of water and iced tea yesterday. each glass of water contained 8 ounces. each glass of iced tea contained 12 ounces. all together, he drank 96 ounces. the system of equations below models this situation. x + y = 10 8 x + 12 y = 96 how many glasses of water did mark drink yesterday? a.3 glasses b.4 glasses c.5 glasses d.6 glasses
