What I Can Do Activity 7: Light Me Up Description: This activity will enable you to solve real-life problems involving linear functions Directions: Consider the situation below and answer the questions that follow.
Zeke lights a 9-inch long candle. He records the length of the candle. y represents the length while x represents the hours.
Number of Hours Candle Burns (x hours)
0 | 1 | 2 | 3 | 4
Height of the Candle (y inches)
9 | 7 | 5 | 3 | 1
1. What is the dependent variable? Explain your answer.
2. What is the independent variable? Explain your answer.
3. Based on the completed table, would the relation represent a line?
4. What is the y-intercept? Explain your answer 5. What is the slope? Explain your answer
6. Write the linear equation.

Answer:
1. A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation
2. An independent variable is a variable that represents a quantity that is being manipulated in an experiment. x is often the variable used to represent the independent variable in an equation
3.where is the table?
4.sorry i cant get it
5. A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable
