The equation of a line in the slope-intercept form is:


y=mx+b

Where m is the slope and b is the y-intercept. These values are given, then the equation of the line is:


y=4x-4

To graph it, we need to know the coordinates of at least two points on the line.

Whan x=0, then y is:


\begin{gathered} y=4\cdot0-4 \\ y=0-4 \\ y=-4 \end{gathered}

Thus, the first point is (0,-4).

When x=1, then y is:


\begin{gathered} y=4\cdot1-4 \\ y=4-4 \\ y=0 \end{gathered}

The second point on the line is (1,0).

If we draw these points in the coordinate plane, we can draw a line that passes through them, and this will be the graph of the line.

It looks like this:
