The line passes through the point (-2,-5) and has a slope of -3.

JulsSmile [24]

Answer:

y = - 3x -11

Step-by-step explanation:

(x₁ , y₁) = (-2 , -5) & m = -3

y - y₁ = m (x - x₁)

y - [-5] = (-3)(x -[-2])

y + 5 = (-3)(x + 2)

y + 5 = -3x - 6

y = -3x - 6 - 5

y = - 3x -11

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai

beks73 [17]

Let $s_n$ denote the number of seats in the $n$ -th row. $s_n$ is arithmetic, so

$s_n=s_{n-1}+d$

for some constant $d$ .

We're told $s_5=22$ and $s_{10}=37$ , so that

$s_{10}=s_9+d$

$s_{10}=(s_8+d)+d=s_8+2d$

$s_{10}=(s_7+d)+2d=s_7+3d$

and so on up to

$s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3$

The pattern continues:

$s_5=s_4+3$

$s_5=(s_3+3)+3=s_3+2\cdot3$

and so on up to

$s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}$
