The coordinates of the vertices of quadrilateral abcd are a(−4, −1) , b(−1, 2) , c(5, 1) , and d(1, −3) . drag and drop the choices into each box to correctly complete the sentences.

Hi there, KawallPotato! :)

Finding the slope of a line is finding the rise over run, or the change in y over the change in x. Let me show you what I mean.

Slope = change in y / change in x

Or in other words,

Let's try it with AB. The first thing to consider is the placement of the letters. The blank space is asking for the slope of point A to point B, which means that the coordinates of A are your y₁ and x₁ values and the coordinates of B are your y₂ and x₂ values.

Put them in the equation like this:

2 - (-1) is a double negative, so it becomes 2 + 1, which is 3.

-1 - (-4) turns into -1 + 4 for the same reason. The change in x is also 3.

, so the slope of line AB is 1.

Using the same method, we can solve the next three problems.

Coordinates of B: (-1, 2)

Coordinates of C: (5, 1)

Slope:

The slope of BC is -1/6.

Coordinates of C: (5, 1)

Coordinates of D: (1, -3)

Slope: , so the slope is 1.

Coordinates of A: (-4, -1)

Coordinates of D: (1, -3)

Slope:

The slope is .

Quadrilateral is not a parallelogram because it has only one pair of parallel opposite sides.

I hope this was helpful. Have a great day. :D

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
