Determine whether KM and ST are parallel, perpendicular, or neither. K (-3, -7), M(3, -3), S(0, 4), T(6, -5)

So, KM and ST are perpendicular  lines

Step-by-step explanation:

Find the slope of KM and ST.

K (-3, -7), M(3, -3)

Slope of KM =

S(0 , 4)  & T(6 , -5)

Slope of ST =

Slope of KM * slope of ST =

                                           = -1

So, KM and ST are perpendicular  lines

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
