(3, 1 ) is a solution
Step-by-step explanation:
To determine if the given points are solutions, substitute the x and y values into the left side of the equation and if equal to the right side then they are solutions.
(3, 1 )
3 + 4(1) = 3 + 4 = 7 = right side , then a solution
(2, 1 )
2 + 4(1) = 2 + 4 = 6 ≠ 7 ← not a solution
