For which of the following pairs of sets is it true that n(D) + n(E) = n(DUE)? a. D = {1, 2, 3, 4), E = {5, 6, 7, 8}
b. D = {}, E = {1}
c. D = {a, b, c, e), E = {c, b, a, d}

Slope: 3/5

Step-by-step explanation:

In this question, we have to find the slope of line "u".

We know that line "u" is parallel to line "t", which means that the slopes are going to be the same.

To find your answer, we would have to find the slope of line "t" using the points given.

Plug in the points to the slope equation, y2-y1/x2-x1 and solve.

Solve:

5 - 8/3 - 8

-3/-5

The negatives on both sides of the fraction cancel.

3/5

The slope of line "t" is 3/5, which means that the slope of line "u" is also 3/5.

Your answer would be 3/5
