Answer:
The coordinates of point B are (-2, 2).
Step-by-step explanation:
Given:
Point A (2,−8)
Point C (−4,7)
Point B divides the line AB such that the ratio AB:BC is 2:1.
To find: The coordinates of point B.
Solution:
We can use the segment formula here to find the coordinates of point B which divides line AC in ratio 2:1
Where is the co-ordinate of the point which
divides the line segment joining the points and
in the ratio
.
m = 2
n = 1
As per the given values
Putting the values in the formula:
So, <em>the coordinates of point B are (-2, 2)</em>.
Hi :)
I'd start by adding 5 to both sides of the equation. That would make the equation easier.
The next step is to get rid of the radical sign.
Which operation will undo the square root? Squaring.
So that's why we square both sides:
And Now we just divide both sides by 2
