Final answer:
The slope of the line represented by the equation 15x - 5y = 10 is 3.
Step-by-step explanation:
To find the slope of the line given by the equation 15x - 5y = 10, we need to express it in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
First, we solve for y:
15x - 5y = 10
-5y = -15x + 10
y = 3x - 2
The coefficient of x in this equation is the slope (m) of the line. Thus, the slope of the line is 3. So the correct answer is: A) 3
