Question

(i) Segment AB is parallel to Y axis and coordinates of point A are (1, 3) then find
the co-ordinate of point B.​

Answer 1

Answer:

(-1, -3)

Step-by-step explanation:

let AB intersect x axis at O, then OA=OB( radius) .

so B must be (-1,-3)

Answer 2

Step-by-step explanation:

As we know that in y axis the value of y is zero(0).

so,

we have, A(1,3) and let B(X,0)

now, using distance formula...

AB =

$\sqrt{ {(x2 - x1)}^{2} + \: {(y2 - \: y1) }^{2} }$

AB² = (x-1)² + (0-3)²

AB² = (x² - 2x + 1) + (0² - 0 + 9)

AB² = x² - 2x + 1 + 9

AB² = x² - 2x + 10
