Find an equation for the family of linear functions with slope 4. (Use the standard coordinate variables x and y. You may use m for the slope and b for the y-intercept as needed.)

To find the equation for the family of linear functions with a slope of 4, we start with the general form of a linear equation:

\[
y = mx + b
\]

Here, \( m \) represents the slope and \( b \) represents the y-intercept.

Given that the slope \( m = 4 \), the equation for this family of linear functions becomes:

\[
y = 4x + b
\]

In this equation, \( b \) can be any real number, representing different members of the family of functions that all have the same slope but different y-intercepts.

Here are 5 related questions:
1. How does changing the value of \( b \) affect the graph of the function?
2. What is the geometric interpretation of the y-intercept in a linear function?
3. How would you find the x-intercept of a line in this family of functions?
4. Can two different linear functions in this family intersect? If so, where?
5. How does the equation change if the slope were different, say \( m = -2 \)?

**Tip:** The slope \( m \) determines the steepness of the line, while \( b \) determines where the line crosses the y-axis.
