1. if the equation y=3× +2is changed to y= -3× +2 how will the graph of the line change?

a. it will shift down 3 units
b. it will shift left 1/3 units
c. it will slope in the opposite direction
d. the new line will be parallel to the original line.

2. you write the equation 2w+2w+w+w=90 for the word problem. you solve and get 15. what is the answer to the problem

a. the area is 450 in^2
b. the width 15 inches
c. the area is 112.5 in^2
d. the length is 30 inches

It is a . The area is 450 in^2

If the current demand is along the D2 curve, then increasing demand would have it shift to the right (indicating more quantities are demanded for a fixed price). So D3 would be to the right of D2

As shown from D1 to D2, the equilibrium price increases. The same can be said going from D2 to D3 as well. In other words, the higher the demand, the higher the equilibrium price. Which is what we'd expect: the more people want a certain item, the more they're willing to pay for it (esp if its in short supply).

Final Choice B) Add D3 to the right of D2; leads to increase in demand and equilibrium price
