Question 10 Write an equation of a line that passes through (− 1, 1). (This has many answers)

Answers 1 a. -1/2 b. -1 c. -4 2 a. ¼ b. 1 c. -1/10 3. y = 4. 5 x – 15 5. y = 1/2 x + 4 6. y + 1 = -5(x – 4) 7. y = 25 x + 500 8 a. m = -2, b = -7 b. m = ½, b = 3 9 a. y = 1/4 x; 9 b. y = 2 x; 3/4 6 10. There are many answers to this question. An example would be y = -3 x – 2.
