Write a linear equation for the graph

y=-1/2x+0

Step-by-step explanation:

First, find the slope by choosing two points and counting up and over (rise over run). Then, find where the line crosses the y-axis to get the y-intercept.

For the two points, let's choose (0,0) and (-2,1). You can either count up and over to get slope, or you can use the slope formula which is y2-y1/x2-1x.

1-0/-2-0 = -1/2.

Since this line represents a negative slope, your slope is -1/2.

Now, looking at the graph, you can see that the line crosses the y-axis at 0. This is your y-intercept.
