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

answer blank #1: the slope of ab is

answer blank #2: the slope of bc is

answer blank #3: the slope of cd is

answer blank #4: the slope of ad is

answer blank #5: quadrilateral abcd is a (choose: trapezoid or parallelogram)

for answer blank #5 make sure you spell your answer correctly!

Step-by-step explanation:

Given that coordinates of the vertices of quadrilateral ABCD are A(-1, -1), B(-3, 3), C(1, 5), and D(5, 2).  

Slope of line is given as

Using above formula,

The slope of AB is

The slope of BC is

The slope of CD is

The slope of AD is

You can see that Only Line BC and Line AD are parallel.

Therefore, Quadrilateral ABCD is a Trapezoid.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
