Question

Seg LM is parallel to X-axis and co-ordinates of point L are (4, -5) then co-ordinates of point M can be _______ . (A) (4, 5) (B)(4, 0) (C) (-6, -5) (D) (-5, 0)​

Answer 1

Answer:

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)
