A
(1, 0.2)
B
(1, 0.4)
C
(1, 2.0)
D
(1, 40)
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Draw a straight line from point S to meet the y-axis, which cuts it at 2, and do the same for the x-axis which cuts it at 1. Therefore the coordinate of the point S is (1, 2)
NOTE: for this graph, each box(square) = 2.5cm on both axes.
