According to the proportional relationship, how much money did the song bring in from sales in the first week if the pop star ea
rned $800 that week?
Describe what the point (0,0) on the graph represents in terms of the situation being described by the graph.
Which point on the graph represents the amount of money the pop singer gets for $1 in money brought in from sales of the song by the store? (*This is the unit rate)
$800 = x/_____ (For prt.1)

Answer:
Step-by-step explanation:
Equation of a line is given as
Where,
m = slope of the line =
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.
Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m
b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>
