Answer:

Explanation:
By definition the Slope-Intercept form of an equation of a line is:

Where "m" is the slope of the lines and "b" is the y-intercept.
You have the following equation of the line given in the exercise:

Then, in order to write it in Slope-Intercept form, you need to solve for the variable "y".
The steps are shown below:
1. You must apply the Addition property of Equality adding
to both sides of the equation:

2. Finally, you must apply the Division property of Equality dividing both sides of the equation by 3. Then, you get:
