Answer:slope = -3
Step-by-step explanation:The slope of the line can be calculated using the following formula:
slope =

From the graph, we can get two points as follows:
point (0,4) representing (x1 , y1)
point (1,1) representing (x2 , y2)
Substitute with the givens in the above equation to get the slope as follows:
slope =
