4x+4y=-9
first change into yintercept form
y=-x-9/4
 to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively

\bf \begin{array}{ccllll}&#10;term&value\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;a_1&9.5\\&#10;a_2&11.5\\&#10;a_3&13.5\\&#10;a_4&15.5\\&#10;...&...&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;a_n=a_1+(n-1)d\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term}\\&#10;d=\textit{common difference}&#10;\end{cases}

notice, the first term is 9.5
from there it goes to 11.5, well, how much is it being added to get 11.5?
well 9.5 + 2, is 11.5, so it was added 2 to 9.5

then it goes from 11.5 to 13.5, namely, 11.5+2 = 13.5
and then 13.5+2 = 15.5 and so on

so, the "common difference" or the common addition value, is 2
how do you find the nth term?

well  \bf a_n=9.5+(n-1)2\iff a_n=9.5+2(n-1)
