Question

Which is the graph of FX equals 4X

Answer 1

We need the graph of the function:

`f(x)=4x`

Comparing with the slope-intercept line function:

`f(x)=mx+b`

Where the slope is m and the y-intercept (the point where the line crosses the y-axis) is b.

In this case:

`\begin{gathered} m=4 \\ b=0 \end{gathered}`

m=4 means that each step the graph advances 4 in y (vertical direction) and 1 in x (horizontal direction)

and b=0 means that the graph crosses the y-axis at y=0 --> the origin

The graph is as follows:
