Question 69301This question is from textbook Algebra I
: Between the ages of 11 and 18, you should get at least 1200 milligrams of calcium each day. One ounce of mozzarella cheese has 147 mg of calcium, and one ounce of swiss cheese has 210 mg. Suppose you wanted to eat no more than 8 ounces of cheese.
Draw a graph showing the possible amounts of each type of cheese you can eat and still get your daily requirement of calcium. Let x be the amount of mozzarella cheese and y be the amount of Swiss cheese.This question is from textbook Algebra I

Between the ages of 11 and 18, you should get at least 1200 milligrams of calcium each day. One ounce of mozzarella cheese has 147 mg of calcium, and one ounce of swiss cheese has 210 mg. Suppose you wanted to eat no more than 8 ounces of cheese.
Draw a graph showing the possible amounts of each type of cheese you can eat and still get your daily requirement of calcium. Let x be the amount of mozzarella cheese and y be the amount of Swiss cheese.
------------------------------
Calcium: 147x + 210y >=1200
Ounces: x + y <= 8
-------------------------
To graph, put them in slope-intercept form:
y= -x+8
y <= (-147/210)x +(1200/210)
