Given 2 x - y = 0,
Re-arranging, y =2 x
comparing y = mx + c,
m = 2 ,
[tex]\begin{gathered} \text{The angle of inclination, tan }\theta\text{ = m =2,} \\ \text{ tan }\theta\text{ = 2, } \\ \text{ }\theta\text{ = }\tan ^{-1}\text{ (2 )} \\ \text{ }\theta\text{ = 63.4 degrees (B)} \end{gathered}[/tex]
