Match each graph with its equation. Write down the strategy you used for each
1. Match each graph with its equation. Write down the strategy you used for each. Answers: 1 = 5 = 2 = 6 = 3 = 7 = 4 = 8 = C H B G A F E D x = -3 y = -2x - 1 y = 6 x = 7/2 2x + 3y = 12 -8x + 10y = 40 y = 2x + 1 y = -2 1 4 5 7 8 6 3 2
13. A x + B y = C To put into standard form, just use rules for solving equations. y = 3 x + 2 4 Try these: y = 2x - 1 -2x + y = -1 or 2x + y = 1 y = 1/2 x - 3/2 x - 2y = -3 or -x + 2y = 3 y = 3/7 x - 3/8 -24x + y = -21 or 24x - y = 21
14. WHITEBOARD PRACTICE What are the x and y -intercepts? 3x + 9y = 18 (6, 0) (0, 2) 5x - y = 100 (20, 0) (0, -100) -8 x - 3y = -48 (6, 0) (0, 16) What is the equation of each line? x = - 6 y = - 7 x = 5.5
