The given line has its x-intercept at 8 and the y-intercept at 15. There are many ways to solve for the slope. Here is a relatively simple way. Use the intercept - intercept form of the line which is x/a + y/b = 1, where a and b are the x and y intercepts.

x/8 + y/15 = 1

=> 15x + 8y = 120

Now convert this to slope intercept form y = m*x + c

15x + 8y = 120

=> 8y = -15x + 120

=> y = (-15/8)*x + 120/8

The slope is -15/8

The slope of the given line is -15/8
