Formula for midpoint between two points is M(x,y)
x=(x1+x2)/2 and y=(y1+y2)/2
In our case (x1,y1)=(m,b) and (x2,y2)=(0,0)
x=(m+0)/2=m/2 and y=(b+0)/2=b/2 M(m/2,b/2)
Good luck!!!
No If it was 4 to 3 then yes but 4 can't be multiplied by anything to equal 9
You will need to raise the unit selling price... do you need know by how how much? well it it will have to be a 25% increase for the unit selling price to maintain the groos margin percentage
