**Graphing a Line Through a Given Point with a Given Slope**

In this lesson, we will learn how to graph a line through a given point with a specified slope. 

### Example Problem:

**Graph the line with slope \(\frac{-2}{3}\) passing through the point \((-3, -4)\).**

### Instructions to Solve the Problem:

1. **Identify the Slope and Point:**
   - **Slope (m):** The slope of the line is \(\frac{-2}{3}\).
   - **Point (x₁, y₁):** The given point through which the line passes is \((-3, -4)\).

2. **Plot the Given Point on the Graph:**
   - Find the coordinates \((-3, -4)\) on the Cartesian plane and place a point there.

3. **Use the Slope to Find Another Point on the Line:**
   - The slope \(\frac{-2}{3}\) tells us that for every 3 units you move to the right (positive direction along the x-axis), you move 2 units down (negative direction along the y-axis).
   - Alternatively, for every 3 units you move to the left (negative direction along the x-axis), you move 2 units up (positive direction along the y-axis).

4. **Plotting Using the Slope:**
   - Starting from \((-3, -4)\), move 3 units to the right to \((0, -4)\), then move 2 units down to \((0, -6)\).
   - Another approach: starting from \((-3, -4)\), move 3 units to the left (to \((-6, -4)\), then move 2 units up to \((-6, -2)\).
   - Plot these new points.

5. **Draw the Line:**
   - Using the points you have plotted, draw a straight line through them. This is your required line with the slope \(\frac{-2}{3}\) passing through \((-3, -4)\).

### Visual Aid:

This process is represented on a Cartesian plane. See the accompanying graph which includes coordinate axes marked from -10 to 10 on both the x and y axes. The interface provides tools (pencil) for drawing, an eraser for corrections, and a checkmark for validation once you've completed the drawing.
