Answer:

Step-by-step explanation:

r=-144/216=-2/3

$a_{7}=216(-2/3)^{7-1}\\=216(\frac{-2}{3} )^6\\\\=216(\frac{2^6}{3^6})\\=216\times\frac{64}{729}\\=\frac{512}{27}\\$

ohaa [14]

Answer:

${ \mathfrak{answer \: \dashrightarrow \: { \rm{y = \frac{2}{5} x + 1}}}} \\$

Step-by-step explanation:

• General linear equation:

${ \rm{y = mx + b}}$

m is the slope

${ \rm{m = \frac{3 - 1}{5 - 0} }} \\ \\ { \rm{m = \frac{2}{5} }}$

b is y- intercept

Consinder point (0, 1)

${ \rm{y = mx + b}} \\ \\ { \rm{1 = 0 + b }} \\ \\ { \rm{b = 1}}$
