PLEASE ANSWER FAST AND WITH WORK

Line KL represents a proportional relationship. Point K lies at (18,10)(18,10) as shown on the graph below.
Which ordered pair could represent the coordinates of point LL?

(0.6,0)
(7.5,13.5)
(8,0)
(13.5,7.5)

Answer 1

Answer: (0.6,0)

Step By Step: Since point K lies on the y-axis and has an x-coordinate of 18, point L must have an x-coordinate of 0, so the only possible answer is (0.6,0)

Answer 2

Point K lies at (18,10) on the graph, which means that the coordinates of point LL can be found by multiplying the coordinates of point K by a constant value. Since the line KL represents a proportional relationship, the constant value must be the same for both the x-coordinate and the y-coordinate of point LL. The only choice that satisfies this condition is (7.5,13.5), since both coordinates are the result of multiplying the coordinates of point K by 0.5. Therefore, the coordinates of point LL are (7.5,13.5).
