Question

the linear equation has solution (-2,2) (0,0) (5,-5) then the equation​

Answer 1

Given the points A(−2,2),B(0,0),C((2,2) are solutions of a linear equations.

Let line equation ⟹y=mx+c

Since (0,0) lies on it, c=0 

Since (−2,2) lies on it, 2=−(2)(m)⟹m=−1

So, y=−x

⟹x+y=0 is the equation of line.
