Bad Luck for Beat Patrol The rock group 'Beat Patrol' may soon have to end their career as musicians. Their first
album sold 128 thousand records. Their second album sold 64 thousand. Their third sold 32
thousand, and their fourth only 16 thousand. If their popularity continued to drop at this rate,
how many copies of their ninth album will sell?

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

answer is  

a.

p = 78
