Answer: y = -1/2x + 3
Explanation: b is the point on the y axis where the line intersects . From your picture, that’s 3.
Slope, or m, is RISE OVER RUN. From the photo, you rise up 1, run over 2. That’s 1/2. Since you ran left it’s negative. So the slope, m, is -1/2.
Since you now know m and b, you can write your equation.
y = -1/2x +3
