Parametric Equations

The path of a robotic arm in a two-dimensional manufacturing grid $(X, Y)$ is defined by the parametric equations

\frac{2p - 5}{1 - 4p}, \quad Y = \frac{12}{1 - 4p}, \quad p \neq \frac{1}{4}

where $p\,$ is a control parameter.

a.

Show that the robotic arm moves along a straight line.

b.

The arm's path intersects a safety perimeter defined by the line $Y = 3 X + 10$ . Determine the $X$ -coordinate of this point of intersection.
