Note: Figure not drawn to scale. 3. In the figure above, lines p and q are perpendicular. Line q passes through the origin and intersects line p at (-1, - 2). If (-20, k) is a point on line p, what is the value of k? 12 B16.12) 4 6 8 10 12 14 4. In the accompanying figure, what is the y-coordinate of the point at which the line that is perpendicular to A3 (not shown) at point M crosses the y-axis? 5. A line in the xy-plane contains the points A(c, 40) and B[S, 2c). If the line also contains the origin, what is a possible value of c
