y=-3x+4

Step-by-step explanation:

1. Use the saying "rise over run" to find the slope. Starting at the highest dot, we can count down 3 and across 1. This means the  slope is -3/1 or -3.

2. After finding the slope, we need to find the y-intercept. Locate where the line crosses the y-axis, in this case it is at 4.

3. Finally, plug in these numbers to the slope intercept format: y=mx+b. 'm' is the slope and 'b' is the y-intercept.
