Question

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 1

First you want to find the slope. Pick any two points. (150,200) and (300,100) x2-x1/y2-y1
300-150=150
100-200=-100
150/-100= -1.5
Y=mx+b. M is the slope b is the y intercept
Y=-1.5x+300
