Answer: Second option.
Step-by-step explanation:
The Slope-Intercept form of the equation of the line is:
Where "m" is the slope of the line and "b" is the y-intercept.
You know that the second equation of the System of equations given in the exercise is:
Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:
1. Apply the Distributive property and simplify:
2. Now subtract 6 from both sides of the equation:
3. Subtract from both sides of the equation:
4. Subtract from both sides:
5. Divide both sides by -2:
