Question

Seg AB is parallel to y-axis and co-ordinates of
A are (1, 3) then co-ordinates of point B can be _____
​

Answer 1

Answer:

(1,-3)

Step-by-step explanation:

Slope of y-axis will be not defined because the denominator will be 0.

Since AB is parallel to y-axis, so the slope will be same.

Let the coordinate of point B be (x, y).

Slope of AB=

x−1

y−3

slope of y-axis Slope of y-axis is not defined as the denominator of

x−1

y−3

will also be 0.

so,

x−1=0

⇒x=1

With x=1 here is only 1 option that (D).

Hence, the correct answer is (1,-3) .
