Question

slope and rate of change each of the line segments in the word math are numbered in the graph below. determine if the slope of each line is positive, negative, zero, or undefined. 7. line 1 = 8. line 2 = 9. line 3 = 10. line 4 = 11. line 5 = 12. line 6 = 13. line 7 = 14. line 8 = 15. line 9 = 16. line 10 = 17. line 11 = 18. line 12 =

Explanation:

Step1: Analyze vertical/horizontal slopes

Vertical lines (undefined slope): Lines 1, 5, 9, 10, 12.
Horizontal lines (zero slope): Lines 7, 8, 11.

Step2: Analyze positive/negative slopes

Positive slope (rises right): Lines 3, 5.
Negative slope (falls right): Lines 2, 6.

Answer:

1. Line 1 = Undefined
2. Line 2 = Negative
3. Line 3 = Positive
4. Line 4 = Undefined
5. Line 5 = Positive
6. Line 6 = Negative
7. Line 7 = Zero
8. Line 8 = Zero
9. Line 9 = Undefined
10. Line 10 = Undefined
11. Line 11 = Zero
12. Line 12 = Undefined
