Equation of a Line:

Background:

plot: Matlab has built$-$in plot$($x$,$y$)$ function. Execute "doc plot" command for details.

Color parameter: To change color of a line, you could use an argument while calling plot function. Example: plot$($x$,$y$,\text{'}$r$\text{'})$ where $\text{'}r\text{'}$ stands for red. Color codes are given below.

$\backslash$table$[[$Short Name,Long Name$],[y,$yellow$],[m,$magenta$],[c,$cyan$],[r,$red$],[g,$green$],[b,$blue$],[w,$white$],[k,$black$]]$

Plotting multiple equations: Every time you call plot function, it pops up a new figure window. To plot multiple equations in the same figure, use "hold on;$"$ function after you call plot function.

Grid: "grid on;$"$ command turns on the grid in the figures.

Problem Statement:

$y=mx+b$

a$.m$ is slope

b$.y-$intercept is $b$

c$.x-$intercept is $-\frac{b}{m}$

Implement a Matlab code plotting $3$ different line equations in the SAME plot. ${?}_{(})y=mx+b$ where:

$x$ is between $-10$ and $+10$ with

Linear spacing between values are $0\mathrm{.}1($Hint: Use $x=-10$:$0\mathrm{.}1$:$10)$
