Determine which ordered pair satisfies the system of linear equation


; (1,4) , (2,9) ,(1/2,-1/2)

(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!

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
