Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

![**Understanding Linear Functions through Graph Analysis**
**Problem Statement:**
The graph of a linear function \( f \) is shown to the right.
**Tasks:**
(a) Identify the slope, y-intercept, and x-intercept.
(b) Write the equation that defines \( f \).
**Graph Description:**
The visual representation provided is a graph of a linear equation on a standard Cartesian plane with labeled axes. The graph includes both positive and negative values extending from -5 to 5 on the x-axis and y-axis. The linear function appears as a straight line sloping downwards from left to right, intersecting the y-axis at \( y = 4 \) and the x-axis at approximately \( x = 4 \).
**Questions:**
**a) The slope is** ____ .
(Type an integer or a simplified fraction.)
**Instructions:**
1. To find the slope (\( m \)), use the formula \( m = \frac{\Delta y}{\Delta x} \), where \( \Delta y \) represents the change in the y-coordinates and \( \Delta x \) represents the change in the x-coordinates between two points on the line.
2. Identify the exact y-intercept (where the line crosses the y-axis).
3. Identify the exact x-intercept (where the line crosses the x-axis).
By plugging the values from the graph into these steps, you should arrive at the slope and the full linear equation.
**Solution Steps:**
Starting with the visual details provided, let's solve:
- y-intercept: \( y = 4 \)
- x-intercept: Near \( x = 4 \)
- Choose two points to find the rise over run (slope):
- Point 1: (0,4)
- Point 2: (4,0)
Thus, slope \( m \) is:
\[ m = \frac{0 - 4}{4 - 0} = \frac{-4}{4} = -1 \]
Finally, substitute the identified intercept and slope into the slope-intercept form \( y = mx + b \):
\[ y = -x + 4 \]
