The coordinates of the vertices of quadrilateral abcd are a(-5, 1), b(-2,5), c(5, 3),

and d(2, -1)

drag and drop the choices into each box to correctly complete the sentences.

the slope of ab is

the slope of bc is

the slope of cd is:

and the

slope of ad is

1. quadrilateral abcd is

because

Step-by-step explanation:

To calculate a slope, we need to apply:

Applying formula to each slope:

So, as you can see, there are equal pair of slopes, meaning that they are parallels, which demonstrate that it's actually a quadrilateral figure.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
