Linear Function Bd8479
1. The problem is to analyze the linear function given by the equation $y = -\frac{1}{2}x + 3$.
2. This is a linear equation in slope-intercept form $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.
3. Here, the slope $m = -\frac{1}{2}$ means the line decreases by 1 unit in $y$ for every 2 units increase in $x$.
4. The y-intercept $b = 3$ means the line crosses the y-axis at the point $(0, 3)$.
5. To find the x-intercept, set $y=0$ and solve for $x$:
$$0 = -\frac{1}{2}x + 3$$
$$\frac{1}{2}x = 3$$
$$x = 6$$
So the x-intercept is at $(6, 0)$.
6. The line has no extrema (no maximum or minimum points) because it is linear.
7. Summary:
- Slope: $-\frac{1}{2}$
- Y-intercept: $(0, 3)$
- X-intercept: $(6, 0)$
This line decreases gently from left to right crossing the y-axis at 3 and the x-axis at 6.
