What Is the slope of the line on the graph?
sashaice [31]

Answer:

1/2

Step-by-step explanation:

To find out this problem, you do rise over run to find the slope. First choose two points that are directly sitting on a line. I used (-2,1) and (0,2). Then count the rise, up 1, then the run, over two and that's how you get your answer. :)
