Given :
Suppose the distributor charges the artist a $40.00 cost for distribution, and the streaming services pays $4.00 per unit
Step-by-step explanation:
Cost of distribution is the fixed cost . y intercept is the fixed cost.
Distributor charge is 40. So y intercept = 40
Payment per unit is the slope that is 4 per unit.
slope =4
Slope intercept form is 
Where m is the slope and b is the y intercept.
y intercept b=40. and slope m=4
So the equation of the line is 
The graph of the line is included below
To find the number of streams that pay for distributor charges , we set
the equation equal to 0 and solve for x

10 streams you pay for distributor charges.
Given profit is 750,000. so y=750,000
We need to find out x the number of streams

we know that 1 unit = one thousand streams
so , Approximately 187 streams
Answer:
y intercept = 40
slope =4
y=4x+40
10 streams you pay for distributor charges.
187 streams to get profit $750,000
