Suppose that the supply function for honey is p=S(q)=0.2q+22, where p is the price in dollars for an 8-oz container and q is the quantity in barrels. Suppose also that the equilibrium price is $4.40 and the demand is 3 barrels when the price is $5.80. Find an equation for the demand function, assuming it is linear.

From a text book:

"The general form of a linear equation in two variables is$ax+by+c=0$ or, $ax+by=c$ where a,b,c are real numbers such that $a\ne 0,b\ne 0$ and x,y are variables.
(we often denote the condition a and b are not both zero by ${a}^{2}+{b}^{2}\ne 0$ .)"

I don’t understand this last condition.

How can we say that${a}^{2}+{b}^{2}\ne 0$ represents the condition that a and b are not both zero.

Let a=0,b=1, then also this condition fulfills.

a) Determine a condition under which (x, y, z) is a linear combination of [-3, 5, -3], [-9, 11, -3], [-6, 8, -3]? Your condition should take the form of a linear equation.

Im so confused?? I have the theorem that every vector (x, y, z) in$R}^{3$ is a linear combination of $x(1,0,0)+y(0,1,0)+z(0,0,1)$ .

The three forms of linear equations you have studied are slope-intercept form, point-slope form, and standard form. Explain when each form is most useful.
