Find a relation between x and y such that the point (x,y) is equidistant from the points (-4,-1) and (5,-2).
Please do answer with an explanation.
Answers
Step-by-step explanation:
(X+4)^2 - (y+1)^2 = (X-5)^2 - (y+2)^2
X2+16+8x-y2-1-2y=X2+25-10x-y2-4-4y
16-1-25+4+8x+10x-2y+4y=0
-6+18x+2y=0
18x+2y=6
6x+y=3

❏ Midpoint of a line segment is such a point that divides line segment in 2 parts of equal measure.
❏ Here is a formula that is unique relation between co-ordinates of midpoints and endpoints of line segment.
- Mid - Point : (x , y)
Let the given co-ordinates of endpoints be :
- End Point 1 : (x₁ , y₁)
- End Point 2 : (x₂ , y₂)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
➠ End Point 1 : (x₁,y₁) = (-4,-1)
➠ End Point 2 : (x₂,y₂) = (5,-2)

❖ Here we go with relation of x-coordinates.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
❖ Here we go with relation of y-coordinates.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Now by adding Equation : 1 and Equation : 2 ,
