Help please due tomorrow

1. Consider a particle following the parametric equations

                                                                                                           $x = 2t+1$, $ y = 3t+2$
as well as points $P_1$, $P_2, P_3,$ and $P_4$ :

Say that our particle is at $P_1$ at time $t_1$, our particle is at $P_2$ at time $t_2$ , our particle is at $P_3$ at time $t_3$ , and our particle is at $P_4$ at time $t_4$ . Enter times $t_1, t_2, t_3$, and $t_4$ in that order.

2. Consider a particle following the parametric equations

                                                                                                        $x = 2t+1$

                                                                                                        $y = 3t+2$
What is the speed of this particle? (You may assume it's constant at all times.)
