The equation of a line can be written in slope-intercept form, which is:

\[
y = mx + b
\]

Where:
- \(m\) is the slope.
- \(b\) is the y-intercept.

In this case, the slope \(m = 4\), and the y-intercept \(b = -4\). So, the equation of the line is:

\[
y = 4x - 4
\]

To graph this:

1. Start by plotting the y-intercept \((0, -4)\) on the graph.
2. Use the slope \(4\), which means for every 1 unit you move to the right (in the positive x-direction), you move up 4 units.
   - From \((0, -4)\), move to the point \((1, 0)\) (since going right by 1 and up by 4 brings you there).
3. Draw the line through these two points.

2. How do you find the slope from two points on a graph?
3. How does the slope affect the angle of the line?
4. Can you graph a line given the slope and a point other than the y-intercept?
5. How do you write the equation of a line given two points?

**Tip:** When graphing lines, always start by identifying the y-intercept, then use the slope to find other points along the line.
