Answer
y = -2x + 3
Work Step by Step
Looking at the graph, we can use the two marked points (0,3) and (1,1) to find the slope, which comes out to -2.
We can then find the y-intercept just by looking at the graph, and seeing that it is at (0, 3)
Then, we put it in to standard form using the y = mx + b formula, to get the answer: y = -2x + 3
