Question

Write a linear equation having solutions of the type (-2, -2), (0, 0) and (2, 2)​

Answer 1

Answer:

x-y = 0

Step-by-step explanation:

let us suppose that the required equation is ax+by+c=0

as (0,0) is a solution therefore by putting x=0 and y=0 we get

c= 0

so now we know that

ax+by=0 is the required eq (c=0)

therefore

ax=(-by)

putting x=y=2

2a=(-2b)

therefore a=1 and b= -1

so the req eq is x-y = 0
