Answer:
2/-8 = -1/4 or -0.25 in decimal
Explanation:
To find the slope take two distinguishable points on the graph(integer values preferred).
Find the difference in the y values and divide by the corresponding difference in the x values
You can identify 2 points with integer coordinates as
(-5, 3) and (3, 1)
Difference in y values = 3 - 1 = 2
Corresponding difference in x values : -5 - 3 = -8
So slope is 2/-8 = -1/4 or -0.25 in decimal
