I'm confused about the whole process for this. Also unsure about how to determine the direction.

Parametric equations and a parameter interval for the motion of a particle in the xy-plane are given. Identify the particle's path by finding a Cartesian equation for it. Graph the Cartesian equation. Indicate the portion of the graph traced by the particle and the direction of motion. x = 5t + 2, y = 15t + 1, - co
