The functions f(x) and g(x) are shown below f(x) = 5x g(x) = 5x which statement best describes the graph of f(x) and g(x)?

The functions supplied appear to be the same? Regardless:

We have the equation y = 5x.
Therefore the gradient of this graph will be 5, so for every 1 increase in the y axis, there will be 5 in the x.

It will appear as a straight line passing through the origin and the point (1, 5).

It is the graphs will both their y-intercepts= to 5
