Answer :
Word Count : 367
To solve this using the DDA (Digital Differential Analyzer) line drawing algorithm, we follow these steps manually: Step 1: Identify the coordinates of the endpoints ( P(x_0, y_0) = (12, 4) ) ( Q(x_1, y_1) = (4, 10) ) Step 2: Calculate the differences [ \Delta x = x_1 - x_0 = 4 - 12 = -8 ] [ \Delta y = y_1 - y_0 = 10 - 4 = 6 ] Step 3: Determine the number of steps [ \text{steps} = \text{max}(|\Delta x|, |\Delta y|) = \text{max}(8, 6) = 8 __________ ________ __________ _____ _____ _________ _________ ____ _____.
