Explain ? i would appreciate someone's : )

B is the answer for ur question

Okay,
D.
Here is the equation to find the slope:
m=∆y/∆x
Where ∆y=y2-y1
∆x=x2-x1
Also, here is the equation:
y=mx+b
Where y represent y-intercept
Look at the the line we see that point (0,20) must be y-intercept.
To find slope, I choose two points from the graph:
(1,23)
(0,20)

m=(20-23)/(0-1)
m=-3/-1
m=3
Here is the complete
y=3x+20. Hope it help!

221,500 is the answer
