Summary

its easy just follow the instruction well...

Description

1. -2 is the slope; the line goes through the point (-5, 5) 5. y + 1 = -6(x – 7) 9. y + 3 - -9(x + 11) 13. The form is y – y1, so the left side should be y – (-5) or y + 5; y + 5 = -2(x – 1) 17.

21. y – 4 = (x – 1) or y – 1 = (x + 2) 25. 29. A point was not substituted into the equation, the y coordinates of the two points were substituted. The equation should be 33. No, there isn’t a consistent difference in the y-values 37. a. y = 130x + 530 b. $1570

41a. The cost increases at a constant rate of $0.49 per prints, so it is a linear equation b. y – 1.98 = 0.49 (x – 1) c. $1.49 d. $1.79...
