Question

How can I write the equation of this line ?

Answer 1

`\begin{gathered} (x)/(a)+(y)/(b)=1 \\ \\ (x)/(2)+(y)/(4)=1 \\ \\ multiply\text{ through by 8 to clear fractions } \\ \\ 8((x)/(2))+8((y)/(4))=8*1 \\ \\ 4x+2y=8 \end{gathered}`

The equation of the line can be written as 4x+2y=8 or 4x+2y-8=0
