(x-4)/(3)(x+5)(x-5)
In order for the rational expression to be undefined, the denominator must be equal to 0.
Thus, set 3(x+5)9(x-5)=0
x=5 and -5
329.6 if you don't have to round it and 330 if you do have to round it.
The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:

.
Thus, the slope in A is

.
The slope in B is

.
Now, to compare 7/6 to 5/3, we can write the second fraction as 10/6.
So, the slope in A is larger than the slope in B.
Answer: A
