Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Answer:
[tex]y=-\frac{2}{3}x +300[/tex]
Step-by-step explanation:
y=mx+b
we have two points
point A=(0,300)
point B=(450,0)
slope=m=[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
m=[tex]\frac{0-300}{450-0}[/tex]
m=-2/3
we need to find "b"
using point A=(0,300), we have
300=0+b
b=300
finally we have
[tex]y=-\frac{2}{3}x +300[/tex]
