Change the following equation of a line into slope-intercept form.x + 3y = 9

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

To convert the given equation x + 3y = 9 into slope-intercept form, follow these steps:

1. Start with the given equation: x + 3y = 9
2. Subtract x from both sides to isolate the term with y: 3y = -x + 9
3. Divide every term by 3 to solve for y: y = -1/3x + 3

So, the equation of the line in slope-intercept form is y = -1/3x + 3.
