Answer :
The standard form of a linear equation is given by:
[tex]\begin{gathered} Ax+By=C \\ A\in\R \\ B\in\R \\ C\in\R \end{gathered}[/tex]So:
For:
[tex]y=1.125x+1.431[/tex]We need to isolate the constant term, so subtract 1.125x from both sides:
[tex]\begin{gathered} y-1.125x=1.125x+1.431-1.125x \\ -1.125x+y=1.431 \end{gathered}[/tex]Answer:
-1.125x + y = 1.431
