Yes it is.
For every value of 'x' you can name, the value of 'y' is 5 .
If you mark several of those points on a graph, you see that
they form a straight line, which is horizontal and crosses the
y-axis at the point where 'y' is 5.
If the equation were not a linear one, its graph wouldn't be a straight line.
It's the triangle 30° - 60° - 90°.
The sides are in proportion 1 : √3 : 2 (look at the picture).
Therefore we have:
