Describe and sketch the surface in double-struck R3 represented by the equation y = 8x. SOLUTION The equation represents the set of all points in double-struck R3 whose y-coordinate is 8 Correct: Your answer is correct. times their x-coordinate, that is, {(x, 8x, z) | x is in double-struck R, z is in double-struck R}. This is a Correct: Your answer is correct. plane that intersects the xy-plane in the line y = 8 Incorrect: Your answer is incorrect. , z = 1 Incorrect: Your answer is incorrect. . The portion of this plane that lies in the first octant is sketched in the figure.
