Answer:

(2, - 1 )

Explanation:

to determine which point belongs on the line, substitute the x- coordinate into the right side and if the value obtained is equal to the y- coordinate then it lies on the line.

(1, 3 ) : y = 2(1) - 5 = 2 - 5 = - 3 ≠ 3 ← not on line

(0, 7 ) : y = 2(0) - 5 = 0 - 5 = - 5 ≠ 7 ← not on line

(2, - 1 ) : y = 2(2) - 5 = 4 - 5 = - 1 ← lies on line

(3, - 11 ) : y = 2(3) - 5 = 6 - 5 = 1 ≠ - 11 ← not on line
