Answer:
-1.25
Step-by-step explanation:
To find the slope you must use 2 points. For this graph, two points that work are (0,5) and (4,0). Then find the rise over run, which is the change in y over the change in x. Do this by using the slope formula, [tex]\frac{y_{2} - y_{1} }{x_{2}- x_{1} }[/tex]. Once plugged in this should simplify to -5/4. In decimal form, this equals -1.25.
