Step-by-step explanation:
Let the required point be p(X, y) and let the given points be A(–5,4) and B(–1,6).
PA = PB
PA² = PB²
(–5–X) ² +(4–Y)² =( –1–X)²+(6–y) ²
(25+x²+10x) + (16+y²–8y) = (1+x²+2x) +(36+y²–12y).
x²+y²+41+10x–8y = x²+y²+37+2x–12y.
x²+y²+41+10x–8y–x²–y²–37–2x+12y = 0.
4+8x+4y = 0.
8x+4y = –4.
4(2x+y) = –4
2x+y = –1
y=–1–2x.
Hope it helps you
