Question 1181539


A linear function is a function whose graph is a straight line, that is, a polynomial function of degree {{{zero }}}or {{{one}}}.

 A linear function has the following form:
{{{ y = f(x) = mx+ b}}}  where {{{m}}} is a slope and {{{b}}} is y-intercept

A linear function has one independent variable and one dependent variable. 
The independent variable is {{{x}}} and the dependent variable is {{{y}}}.




1. {{{f(x)=-6x-7}}}
is a linear function
 degree: {{{1}}}
slope:{{{-6}}}
y-intercept:{{{-7}}}

2. {{{f(x)=3}}}=>  a horizontal line

is a linear function
 degree: {{{0}}}
slope:{{{0}}}
y-intercept:{{{3}}}


3. {{{f(x)=x-4}}}
is a linear function
 degree: {{{1}}}
slope:{{{1}}}
y-intercept:{{{-4}}}

4.{{{ f(x)=5x-3}}}

is a linear function
 degree: {{{1}}}
slope:{{{5}}}
y-intercept:{{{-3}}}
