Find the slope of the line

What is the slope of the linear equation  3y - x = 9?

Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept

3y - x = 9   {given equation}
3y = x + 9   {added x to each side}
y = (1/3)x + 3   {divided each side by 3, to get into slope-intercept form}

slope = 1/3
