Question

determine which ordered pair satisfies the system of linear equation
$y = 3x - 2$
$y = - x$
;(1,4) , (2,9) ,(1/2,-1/2)


​

Answer 1

(1/2,-1/2)

You have to plug in the x point into the equation and the solution to that must equal your y point the only one that works for this is (1/2,-1/2).

-1/2=3(1/2)-2
-1/2=3/2-2
-1/2=-1/2. Works

-1/2=-(1/2)
-1/2=-1/2. Works


Hope this helps!
