Answer B.
Explanation: The formula to find slope is as follows (y2-y1) / (x2-x1). You fill in the x and y coordinates to the corresponding spot. Meaning, you would place the 2nd y value, which is 7/3, at y2. Do this for the rest of the values. After filling in each value, you would then subtract accordingly, leaving you with the slope value. Hope this helps.
