ANSWER

Step-by-step explanation
We want to put the equation in slope-intercept form:

The general form of the slope-intercept form of a linear equation is:

To do that, divide both sides of the given equation by 15:

From the slope-intercept form of the linear equation, m represents the slope while b represents the y-intercept of the equation.
Comparing the given equation to the general equation, we see that the slope of the equation is:

That is the answer.
