2. Real World Situation
I went to the store to buy candy. They sold candy for $0.75 per pound. If I had $5.00, how many pounds of candy could I buy?

3. Linear Function
Y = .75x
Y represents the cost in dollars(how much money I have)
X represents the number of pounds of candy.

4. Table Pounds (x) Cost (y) 1 .75 2 1.5 3 2.25 4 5 3.75 6 4.5 7 5.25 8 91
.75 2
1.5 3
2.25 4 5
3.75 6
4.5 7
5.25 8 9
6.75 10
7.5

5. Graph

6. Analyzing the Graph Rate of change: .75 Initial Value: 0
Our graph is increasing
We could find the slope from our equation (y=.75x) or by picking two points and using the formula to find slope (slope formula: m = [y1 - y2] / [x1 - x2]).
