Answer:
Slope = -1/2, Y-intercept = 1
Explanation:
The line is going downwards, so we know that the slope will be negative.
Next, if you look at the graph closely you can see that the line goes through 1 on the y-intercept and 2 on the x-intercept. That means you go down one, over two; so the slope is -1/2.
Since we've already established that the line goes through 1 on the y-intercept, that's your answer to identity that.
Hope this helps!
