Question

Find the distance of point (-1,3) from the y axis.

Answer 1

Answer:

DISTANCE => 1UNIT

Step-by-step explanation:

**************** HEY DEAR **************

HERE IS YOUR ANSWER....

AM FINDING PERPENDICULAR DISTNCE HERE...

POINT PERPENDICULAR TO THIS POINT ON Y-AXIS IS ( 0 , 3)

SO DISTANCE

=> ROOT { (-1-0)^2 + (3-3)^2 }

=> ROOT 1

=> 1 UNIT..

*************************************************

HEY MATE U HAVE POSTED HALF QUESTION I HERE TOLD U HOW TO FIND PERPENDICULAR DISTANCE BY APPLYING DISTANCE FORMULAS YOU CAN ALSO DIRECTLY CALCULATE THE DISTANCE AS DISTANCE OF THE GIVEN POINT FROM Y- AXIS IS ALWAYS EQUAL TO THE MODE OF THE X CO ORDINATE..

HOPE IT HELPS YOU..

THANKS.

^_^

Answer 2

point P(-1,3)
from y axis i.e Q(0,y)


By applying distance formula
$\sqrt{( - 1 - 0) ^{2} + (3 - y) { }^{2} }$

$\sqrt{1 + 9 + {y}^{2} - 6y }$

$= \sqrt{10 + {y}^{2} - 6y }$
this is the answer

thank u
