Answer:
The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.
Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2. The vertical line is the y axis and the horizontal line is the x axis.
