To find the slope, we need to rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope.

9x - 3y = 15

To isolate the y-term, we need to move the 9x to the other side:

-3y = -9x + 15

To solve for y, we divide both sides by -3:

y = (9/3)x - 15/3

Simplifying further:

y = 3x - 5

From this equation, we can observe that the coefficient of x (3) represents the slope of the line.

Therefore, the slope is 3.
