Answer:
y=-1/2x+1
Explanation:
The slope of the line can be found using the rise over run. The rise is how far it goes up or down the y axis and the run is how far it goes left or right on the x-axis. Then put the rise over run and you have your slope.The rise is going down 1, so the value for rise is -1. The run is going 2 to the right, to the value for run is 2. Then rise over run, you end up with -1/2. To find the y-intercept, look at how many units the line is up from the x-axis on the y axis. The line is 1 unit above the x-axis on the y axis, so the y-intercept is 1. Puting the equation together, you get y=-1/2x+1.
