(-2, 6) is a solution of
x+(1)/(2) y=1

Explanation:

Given equation:

x+(1)/(2) y=1

Case1: substitute the points (-2, 6) in the given equation, we have,

=>
x+(1)/(2) y=1

=>
(-2)+(1)/(2)*(6)=1

=>
(-2)+(6)/(2)=1

=>
-2+3=1

=>
1=1

Case2 : substitute the points (2, -6) in the given equation, we have,

=>
x+(1)/(2) y=1

=>
(2)+(1)/(2)*(-6)=1

=>
(2)+(-6)/(2)=1

=>
2-3=1

=>
$-1\\eq1$

Case 3: substitute the points (-2, -6) in the given equation, we have,

=>
x+(1)/(2) y=1

=>
(-2)+(1)/(2)*(-6)=1

=>
(-2)+(-6)/(2)=1

=>
-2-3=1

=>
-5=1

=>
$-5\\eq1$
