1. Directions: Please check over your answers to the Jigsaw Activity HW Assignment. If you have any questions about the hw, please come see me. I will collect your Jigsaw activity on Wednesday. Please make sure you complete the packet and the homework for each expert sheet.

2. 1. 6 + y = 3x y = 3x – 6 m = 3/1 b = -6 2. 3y = 4x – 9 y = (4/3)x – 3 m = 4/3 b = -3 3. y + 2x = 10 y = -2x + 10 m = -2/1 b = 10 4. 6y = 3x – 12 y = (½)x m = 1/2 b = -2 5. 2x – 4y = 16 y = (½)x – 4 m = 1/2 b = -4 6. 8 – 2y = 6x y = -3x + 4 m = -3/1 b = 4 7. 4 + y = x y= x – 4 m = 1/1 b = -4 8. 2x = y – 8 y = 2x + 8 m = 2/1 b = 8 9. 36 = 18x + 9y y = -2x + 4 m = -2/1 b = 4 Expert Sheet 1

3. 1. Slope 2; y-intercept 5 Work for some problems from p. 372 y = mx + b y = 2x + 5 (4, 0) is the x-intercept so plug x and y into the equation y = mx + b to get the y-intercept(b). y = mx + b 1 = 2(-5) + b 1 = -10 + b +10 11 = b Equation: y = 2x + 11 (x, y)

4. 17. (0, 7), (1, 9) y = mx + b (0, 7) 7 = 2(0) + b 7 = b Equation: y = 2x + 7 18. (0, 3), (2, -1) Equation: y = -2x + 3 (0, 3)  3 is the y-intercept so you do not need to subtutitue into y = mx + b (x, y)

5. 20. (-3, 4), (3, -4) 24. (-3, -1), (1, -4) Work to question 20 & 24 red text p. 372 Use your graphing calculator. Type -4 + (3/4) = -3.25 To change the decimal into a fraction use the math key on your calc., then press enter twice Come see me if you are stuck with any of the problems. (x, y)
