Write an m$-$file that computes y values for two straight lines straight lines based on the formula y $=$ mx $+$ b using the following information.

Define $2$ row vectors x$1$ and x$2$ as follows:

x$1$ a vector that starts at $3$ and ends at $21$ with increments of $2$

x$2$ a vector that starts at $2$ and ends at $19$ with $25$ data points

Calculate the vectors: y$1$ and y$2$ using the equation of a line $($use m$1$ & b$1$ with x$1,$ etc.$)$ given the following slopes and y$-$intercepts:

m$1=0\mathrm{.}25$; b$1=3$

m$2=-2$; b$2=10$

Do not display any of your x or y values to the command window.

Using the array functions and indexing taught in class, determine and output:

$$ The average value of y$1$

$$ the value of x$2$ for the largest value of y$2$
