Answer:

undefined

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

We have points

(-7,2) (-7,-7)

m = (-7-2) /(-7--7)

= -9/(-7+7)

= -9/0

This is undefined

We have points

(-8,-3) (6,-3)

m = (-3--3) /(6--8)

= (-3+3/(6+8)

= 0/14

$a_1=2;\ r=-\dfrac{3}{2}\\\\a_2=a_1r\to a_2=2\cdot\left(-\dfrac{3}{2}\right)=-3\\\\a_3=a_2r\to a_3=-3\cdot\left(-\dfrac{3}{2}\right)=\dfrac{9}{2}\\\\a_4=a_3r\to a_4=\dfrac{9}{2}\cdot\left(-\dfrac{3}{2}\right)=-\dfrac{27}{4}\\\\a_5=a_4r\to a_5=-\dfrac{27}{4}\cdot\left(-\dfrac{3}{2}\right)=\dfrac{81}{8}$
