Answer/Step-by-step explanation:
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)
Let us suppose, we pour x glass of water.
The given jug is of 6 liters. And the glass of water was seven- eighths of a liter. Hence, we have the below equation

Now, in order to solve for x, we will divide 6 with 7/8. So, we have to divide.

Hence, we can pour 7 glass of water. But the 7th glass is not full of water. It is partially full.
Gertie 3/4 mile.
Sarah 2/4 mile.
Gertie ran farther by: 3/4 - 2/4 = (3 -2)/4 = 1/4
Gertie ran farther by 1/4 mile.
Answer:
put a closed for on -1 and go to the left with an arrow
When lines are perpendicular it’s called parallel, it’s when the lines never touch
