4.2.1 Graphing Functions − Worksheet
Example 1: Use the given x -values to write solutions of each equation as ordered pairs. 1. y = 6 x + 2 for x = 1, 2, 3, 4 2. y = − 2 x for x = 1, 2, 3, 4
Example 2: Determine whether each ordered pair is a solution to the given equation.
3. (2, 12); y = 4 x
4. (5, 9); y = 2 x − 1
Example 3: Use the graph of the linear function to find the value of y for each given value of x .
5. x = 1
6. x = 0
7. x = − 1
