Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
