This problem requires drawing geometric lines based on provided instructions and a visual representation. As an AI, I cannot directly draw or manipulate images. To solve this, you would need to: 1. Understand the Grid: The image shows a grid, which implies a coordinate system or at least a way to measure distances and angles. Each small square can be considered one unit. 2. Identify Line 'b': Line 'b' is not explicitly labeled in the provided crops. However, the text refers to 'прямой b' (line b). Based on the context of drawing parallel and perpendicular lines, 'b' must be a reference line. Since line 'm' is drawn and labeled, and point K is also labeled, it's highly probable that either line 'm' or an implied line related to the grid is considered 'b'. If we assume 'm' is not 'b', then we need to infer what 'b' is. Often, in such problems, 'b' might be a horizontal or vertical grid line, or a line defined by two points not explicitly shown but implied by the grid structure. 3. Identify Point 'K': Point K is clearly marked on the diagonal line in the image. It serves as the reference point through which the new lines will be drawn. 4. Draw Line 'c' (perpendicular to 'b'): * Determine the slope of 'b'. If 'b' is a horizontal line, the perpendicular line 'c' will be vertical. If 'b' is a vertical line, 'c' will be horizontal. If 'b' is a diagonal line, its slope can be calculated (rise over run). Let's assume 'b' is the diagonal line that point K lies on, or a line parallel to it. * Find the perpendicular slope. The slope of a perpendicular line is the negative reciprocal of the original line's slope. For example, if slope of 'b' is m, slope of 'c' is -1/m. * Draw line 'c' through point K with the calculated perpendicular slope. 5. Draw Line 'r' (parallel to 'b'): * Determine the slope of 'b' (as done in step 4). * Draw line 'r' through point K with the same slope as 'b'. To provide a precise answer, the exact definition or visual representation of line 'b' is crucial. Without it, any drawing would be speculative. If you can describe line 'b' (e.g., 'it's a horizontal line', 'it's the line passing through points X and Y', 'it's the line with slope 2'), I can provide the instructions for drawing lines 'c' and 'r' more accurately.
