Answer:- It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.
Explanation:-
[tex]\text{Given function: y=4x+8}\\\text{Put x=0, we get y=0+8=8}\\\text{Put x=1, we get y=4(1)+8=4+8=12}\\\text{Put x=2, we get y=4(2)+8=8+8=16}\\\text{Plot the points (0, 8), (1, 12), (2, 16) on graph, we can see they are on a straight line.}\\\\\text{Therefore the given function:y=4x+8 is a linear function}\\\text{Thus, the right option is It is a linear function because the graph} \\\text{contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.}[/tex]
