I am now leaving this app so yeah bc my friends are in a fight so bye everyone

bye loser

Step-by-step explanation:

no one cares hehehe

uhhh okay- bye???

Step-by-step explanation:

A) The rate of change is -30, and it represents the number of songs taken off of her download list each week.
The initial value is 150, and it represents the number of songs she wants to download to begin with.

B) y = -30x + 150

Explanation
A) The rate of change can be found by using the slope formula between the first two points, (0, 150) and (1, 120):
m=(y₂-y₁)/(x₂-x₁) = (120-150)/(1-0) = -30/1 = -30

The initial value is the y-value of the first point on the graph, (0, 150).

B) The equation is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept.  The slope is the rate of change that we found in part A; the y-intercept is the initial value we found in part A.  This gives us the equation y=-30x+150.
