Answer:
a. y = -2x-5
Explanation:
*Don't get confused the y-axis scale is 2
I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.
The graph is negative because it is pointing the opposite way
The slope is 2 because the y-axis has a scale of 2
With these facts you can formulate that the equation would be y = -2x-5
