Answer:
The answer would be y= -2x+1
Step-by-step explanation:
To get this answer, you are going to find the y-intercept and the slope (rise over run). The y-intercept is where the line passes through the y-axis.
When looking at this graph we see the line passes through the y-axis at (0,1) making our y-intercept positive 1.
To find the slope, we are going to find our rise over run. So, essentially, we already know that only answer B has a positive 1, so looking at this slope (using y=mx+b), we see -2. We can just put this over 1 and our rise over run will be -2/1. By counting these spaces on the graph, we can see this matches the points the line passes through.
