Select the correct answer.

Undefined

DONE

Answer 1

Answer: undefined.

Explanation:

Slope of a line having points (a,b) and (c,d) :

`slope =(d-b)/(c-a)`

Given : Point of line z = (2,2) and (2,7)

Slope of line z :
`(7-2)/(2-2)=(5)/(0)=\infty`

Hence, the slope of line z is undefined.

Since , the slope of two parallel lines are same.

Therefore ,the slope of the line parallel to line z is undefined.
