To determine which letter is at position (1, 3) on the graph, we need to refer to the given marking for each quadrant and locate the corresponding letter.
From the information provided:
- The first quadrant is marked with U, T, S, X, R, W, Q.
- The second quadrant is marked with F, V, G, H, A, V.
- The third quadrant is marked with I, K, J, L, O.
- The fourth quadrant is marked with M, N, Z, P, Y.
To find the letter at position (1, 3), we will locate the point on the graph where the x-coordinate is 1 and the y-coordinate is 3.
Since the given coordinates fall in the first quadrant, we will look for the corresponding letter in the marking for the first quadrant. The options for the first quadrant marking are U, T, S, X, R, W, Q.
Therefore, the letter at position (1, 3) would be one of the above options. To determine the specific letter, we need more information or additional context. Based solely on the given options (A, B, C, D), we cannot determine the correct letter.
In order to find the accurate letter, please provide additional information or clarify the question further.
