Work Step by Step

A. The graph has a slope of 1 which means that as the independent variable increased by 1, the dependent also increased by 1. B. The graph has a slope of -2 which means that as the independent variable increases by 1, the dependent variable decreases by 2. C. The graph is a vertical line and is not a linear function as for every x value there is more than 1 y value and so it doesn't pass the vertical line test.
