Explanation:

Step1: Analyze Data Points

We have paired data: President's height (x - axis) and Opponent's height (y - axis). Let's list some key points: (174, 188), (187, 184), (184, 177), (173, 173), (176, 172), (176, 174), (185, 178), (169, 195), (180, 192), (173, 194), (170, 192), (176, 179), (179, 177), (173, 185), (190, 175), (175, 188).

Step2: Compare with Graphs

• Graph A (first graph): As President's height increases, Opponent's height generally increases? Wait, no, let's check the trend. Wait, looking at the data, when President's height is 169 (low), Opponent's is 195 (high). When President's is 170, Opponent's 192 (high). When President's is 173 (multiple times), Opponent's heights vary. Wait, maybe I misread. Wait, the first graph (Graph B? Wait, the labels: the first graph (let's say Graph 1) has x from 160 - 200, y 160 - 200. Let's check the data points. For example, (174, 188): x = 174, y = 188. (187, 184): x = 187, y = 184. (184, 177): x = 184, y = 177. (173, 173): x = 173, y = 173. (176, 172): x = 176, y = 172. (176, 174): x = 176, y = 174. (185, 178): x = 185, y = 178. (169, 195): x = 169, y = 195. (180, 192): x = 180, y = 192. (173, 194): x = 173, y = 194. (170, 192): x = 170, y = 192. (176, 179): x = 176, y = 179. (179, 177): x = 179, y = 177. (173, 185): x = 173, y = 185. (190, 175): x = 190, y = 175. (175, 188): x = 175, y = 188.

Now, looking at the three graphs:

• Graph B (first one): The points seem to have a positive trend? Wait, no, when x (President's height) increases, y (Opponent's) sometimes increases, sometimes not. Wait, maybe the correct graph is the one where the points are plotted correctly. Let's check the x and y ranges. President's height ranges from 169 to 190 (x - axis: 160 - 200 is correct). Opponent's height ranges from 172 to 195 (y - axis: 160 - 200 is correct).

Wait, the first graph (let's assume the left - most graph, labeled as the first option) has points that match the data. For example, (169, 195) would be x = 169, y = 195 (low x, high y), (170, 192) (x = 170, y = 192), (173, 194) (x = 173, y = 194), (180, 192) (x = 180, y = 192), and also points like (173, 173) (x = 173, y = 173), (176, 172) (x = 176, y = 172), (176, 174) (x = 176, y = 174), (179, 177) (x = 179, y = 177), (185, 178) (x = 185, y = 178), (190, 175) (x = 190, y = 175), (187, 184) (x = 187, y = 184), (184, 177) (x = 184, y = 177), (174, 188) (x = 174, y = 188), (175, 188) (x = 175, y = 188), (173, 185) (x = 173, y = 185), (176, 179) (x = 176, y = 179), (173, 173) (x = 173, y = 173), (184, 177) (x = 184, y = 177), (187, 184) (x = 187, y = 184), (174, 188) (x = 174, y = 188).

After carefully comparing the data points with the graphs, the correct scatterplot is the first graph (assuming the left - most graph is the correct one, as per the data distribution).

Answer:

The left - most graph (the first graph among the three options)
