Concept:A point lies on a line if its coordinates satisfy the line's equation.Explanation:Substitute the x and y values of each point into y=−x+4.For (2, 2): 2=−2+4=2. True.For (5, 4): 4=−5+4=−1. False.For (1, 2): 2=−1+4=3. False.For (3, 6): 6=−3+4=1. False.Only (2, 2) makes the equation hold true.Answer:Option A: (2, 2)
