What are the slope and y-intercept of the equation 3y + 6x + 2 = 0?

Understanding the Equation

The given equation is 3y + 6x + 2 = 0. To find the slope and y-intercept, we need to convert this equation into the slope-intercept form, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

Steps to Rearrange the Equation

  1. Start with the original equation:

    3y + 6x + 2 = 0

  2. Isolate the term with y:

    3y = -6x – 2

  3. Now, divide every term by 3 to solve for y:

    y = -2x – rac{2}{3}

Identifying Slope and Y-Intercept

From the rearranged equation y = -2x – rac{2}{3}, we can easily identify the slope and y-intercept:

  • Slope (m): -2
  • Y-Intercept (b): -2/3 (which is approximately -0.67)

Conclusion

To conclude, for the equation 3y + 6x + 2 = 0, the slope is -2 and the y-intercept is - rac{2}{3}. This means that for every unit increase in x, the value of y decreases by 2 units. Additionally, the line crosses the y-axis at the point (0, -2/3).
