$1.$ Create a function called mb$\_$line.m that takes as input two points, identified as $($x$1,$y$1)$ and $($x$2,$ y$2)$ and produces the output of slope and yintercept value.

$2.$ Create a script called use$\_$line.m that does the following

$($a$)$ gets the x and y values for two points on the line $($include request for $-5<=$x$<=5$ and $-5<=$y$<=5)$

$($b$)$ calculates the slope and b value;

$($c$)$ plots a figure with the line using a grid and blue color line

$($d$)$ create a title that includes the equation and the value of slope and yintercept value

$($e$)$ create a label on the x axis that shows the x values of each point defined earlier

$($f$)$ create a label on the yaxis that shows the y values of each point defined earlier

$($g$)$ plot the points as red $"+$ signs" on top of the line

Please note you may need a specific command executed between the two plots to keep the line and its points on the same figure
