Which expression is equivalent to the following complex fraction?

The expression which  is equivalent to the following complex fraction is:

We are given a expression in terms of two variables x and y as follows:

Now, on taking least common multiple in the numerator as well as in the denominator we have:

which on further simplifying is:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
