The document provides the solution to a calculus word problem involving a particle moving along a curve. The problem asks for (a) the rate of change of the y-coordinate when the particle is at (1,2) and the x-coordinate is increasing at 6 units/s, and (b) whether the particle is rising or falling at that instant. The solution takes three steps: (1) taking the derivative of the equation of the curve, (2) plugging in the given values (1,2) and dx/dt = 6, and (3) solving for dy/dt, which is -60/7 units/s. Therefore, the y-coordinate is decreasing,
