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?
