Answer:

y = -1/2x

Step-by-step explanation:

The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0

The slope is -1/2 because as it rises by -10, it runs by 20

Slope is rise/run which is -10/20 which simplifies to -1/2

y = mx + b

b = y - intercept

m = slope

y = -1/2x + 0 or y = -1/2x

If my answer is incorrect, pls correct me!
