Differentiate to find the velocity, then: if it is moving in that direction, then the i component(of velocity) is equal to the j component (of velocity). Kinda like, 45 degrees to both axes means it's lying on the line y=x, and y= j component, x = i component, since y=x, then j component = i component.
