Step-by-step Solution
To graph the line given by the equation
\[
y = -\frac{3}{5} x + 3,
\]
we can follow these steps:
1. **Identify the slope and y-intercept**: The equation is in slope-intercept form \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept. Here, the slope \(m = -\frac{3}{5}\) and the y-intercept \(b = 3\).
2. **Plot the y-intercept**: Start by plotting the y-intercept on the graph. The y-intercept is the point where the line crosses the y-axis. For this equation, the y-intercept is at the point \((0, 3)\).
3. **Use the slope to find another point**: The slope \(-\frac{3}{5}\) means that for every 5 units you move to the right (positive x-direction), you move down 3 units (negative y-direction). Starting from the y-intercept \((0, 3)\):
- Move 5 units to the right to \(x = 5\).
- Move down 3 units to \(y = 0\).
- This gives you the point \((5, 0)\).
4. **Plot the second point**: Plot the point \((5, 0)\) on the graph.
5. **Draw the line**: Draw a straight line through the points \((0, 3)\) and \((5, 0)\). Extend the line in both directions and add arrows to indicate that it continues infinitely.
6. **Label the graph**: Optionally, label the line with its equation for clarity.
The graph should show a straight line that slopes downward from left to right, crossing the y-axis at 3 and the x-axis at 5.
Quick Answer
Plot the y-intercept at (0, 3) and use the slope \(-\frac{3}{5}\) to find another point, (5, 0). Draw a line through these points and label it with the equation \(y=-\frac{3}{5} x+3\).
