Final answer:
The slope of the line described by the equation 28x -12y + 50 = 0 is 7/3.
Step-by-step explanation:
The slope of the line described by 28x -12y + 50 = 0 can be found by rearranging the equation in the form y = mx + b, where m is the slope. Starting with the given equation, we move the terms around:
28x - 12y + 50 = 0
-12y = -28x - 50
y = (28/12)x + (50/12)
This equation tells us that the slope of the line is 28/12 or 7/3.
