Acoordinate plane is shown. which of these is a correct process for plotting the point (3, 6) on the coordinate plane? a. start at the origin. move 3 units up the y-axis, and then move 6 units to the right, plot the point there. b. start at the top of the y-axis, move 3 units down the y-axis, and then move 6 units to the right. plot the point there. c. start at the origin, move 3 units to the right of the y-axis, and then move 6 units up. plot the point there. d. start at the top of the y-axis, move 3 units to the right, and then move 6 units down. plot the point there.
