The experimental data in the table below define $y$ as a function of $x$.

$x$	0	1	2	3	4	5
$y$	2.4	1.1	1	1.4	2.2	3.2

a.) Let $P$ be the point $(1, 1.1)$ . Complete the table below by computing the slope of the secant line $PQ$ when $Q$ is the point of the graph with $x$-coordinate $x_1$.

$x_1$	0	2	3	4	5
slope

b.) Draw the graph of the function for yourself and estimate the slope of the tangent line at $P$
