1. Graph 3x+2y=6. Where do the points cross and how is the pair figured out?
2. Give the degree of 4x.
3. Solve the linear inequality by graphing.
3x + 4y <= 12
x + 3y <= 6
x >= 0, y >= 0
4. The demand and supply equations for a certain item are given by
D = -5p + 40
S = -p^2 + 30p - 8
Find the equilibrium price.
These are several problems involving polynomials and equations: solving, degree, intersection point, and equilibrium.
