y=-2/5x-1

Step-by-step explanation:

I started by looking for the y-intercept of the line, where the line intersects with the y-axis and saw it was -1.

Then I looked at the slope of the line and used the rise/run strategy. From the y-intercept to the point it was 2 units down and 5 units across (2/5) and since it is going down it's negative

Plugging it in: y=mx+b

m=slope

b=y-intercept

y=-2/5x-1

Hope this helps :)
