Concept:A point lies on a line if its coordinates satisfy the line's equation.Explanation:Substitute each given point into 3x−8y=11 and check which gives 11.For (1,−1): 3(1)−8(−1)=3+8=11.This satisfies the equation.The other options do not satisfy the equation.Answer:The point is (1,−1), which is Option B.
