1. Write the equation in slope-intercept form

y + 2= -6(x - 1)

2. Graph each inequality

Y ≥ x-6

X ≥ -6

3. Use the given equation to find the missing coordinates in the tables.

Y = -x - 14

4. Graph each equation. Plot at least five points for each equation.

X - 2y = 6

5. Demand equation.

Helen's Health Foods usually sells 400 cans of ProPac Muscle Punch per week when the price is $5 per can. After experimenting with prices for some time, Helen has determined that the weekly demand can be found by using the equation

                      d = 600 - 40p,

where d is the number of cans and p is the price per can.

a) Will Helen sell more or less Muscle Punch if she raises her price from $5?

b) What happens to her sales every time she raises her price by $1?

c) Graph the equation.

d) What is the maximum price that she can charge and still sell at least one can?
