Question

The graph shown models a linear relation. Use the graph to answer the following questions. The two known points are (0, -3) and (1, -1)

1. What is the value of the dependent variable if the value of the independent variable is 3?
2. Predict the value of the independent variable when the dependent variable is -5.

Answer 1

9514 1404 393

Answer:

1. 3
2. -1

Explanation:

1. The value can be read from the graph. At 3 units to the right of the vertical axis, the line is 3 units above the horizontal axis. The independent variable has a value of 3 at that point.

2. The dependent variable has a value of -5 at the next grid line just below the bottom of the graph shown. The value of the independent variable is -1 at that point.
