Using the graph, we can list the first five terms of the sequence. Notice that the $x$-axis shows us $n,$ the term number. The $y$-axis show us $a_{n},$ the value of the terms. $ 1st term:2nd term:3rd term:4th term:5th term: -3-1135 $

b

$a_{n}=a_{1}+d(n−1)$

$a_{n}=-3+(2)(n−1)$

DistrDistribute $2$

$a_{n}=-3+2n−2$

SubTermSubtract term

$a_{n}=2n−5$

c

$m=x_{2}−x_{1}y_{2}−y_{1} $

$m=4−33−1 $

$m=2$
