Answer
The graphs for all 3 sets are attached below.
A. An increasing straight line
B. A faster decreasing straight line than Set A
C. A vertical line
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.
