7. Line 1 = undefined.
Slope of a vertical line is always undefined. The run is zero as x-coordinate remains the same.
8. Line 2 = 




9. Line 3 = 




10. Line 4 = undefined (slope of a vertical line is always undefined)
11. Line 5 = 



12. Line 6 = 




13. Line 7 = 0
An horizontal line has no rise.
14. Line 8 = 0 (slope of horizontal line is always zero)
15. Line 9 = undefined (slope of a vertical line is always undefined)
16. Line 10 = undefined (slope of a vertical line is always undefined)
17. Line 11 = 0 (slope of horizontal line is always zero)
18. Line 12 = undefined (slope of a vertical line is always undefined)
Answer:
47 / 48
Step-by-step explanation:
Quotient of 3/8 and 2
3/8 ÷ 2
3/8 * 1/2
= 3 /16
1 3/4 * 8/12
7/4 * 8/12
= 56/48
56/48 - 3/16
L. C. M of 48 and 16 = 48
(56 - 9) / 48
= 47 / 48
Answer: 
Step-by-step explanation:
Given
Radius of cylinder 
The height of the cylinder is 
The surface area of a cylinder is 
If only the outer is considered then, the area required is

1mile=5.280
6miles=6*5.280
= 31.680
