I need help with matlab

1. Create a function called mb_line.m that takes as input two points, identified as (x1,y1) and (x2, y2) 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;

(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
