Answer:
B. (4,2)
Explanation:
You can use any graphing calculator, plug in your equation, and then do process of elimination. Search for each given point and if it's on the line of your graph then you know its a solution.
You can also plug in each (x,y) point and if the equation is true, then you know its a solution.
y=-x+6
(2)=-(4)+6
2=2; the equation is true, therefore (4,2) is a point/solution
I recommend using the Desmos graphing calculator, it's super easy to use :)
