Answer:
y=-2x+5
Explanation:
The line is going down so that means your line will be negative, and your slope will be negative too. You get the units from y-axis and the x-axis. The y axis units are 2 and the x axis units are 1, so it'll be 2/1, which is 2. You get the 5 by looking at where the line crosses with the y axis.
