The slope of the line, calculated using the points (2, 65) and (10, 13), is -6.5. This implies that for every $6.50 decrease in price, the quantity of almonds purchased increases by 1 pound. Here option D is correct.
The slope of the line is calculated using the formula:
m = (y2 - y1) / (x2 - x1)
where m is the slope, y1 and y2 are the y-coordinates of two points on the line, and x1 and x2 are the x-coordinates of the same two points.
From the image, we can see that the line passes through the points (2, 65) and (10, 13). Substituting these values into the formula, we get:
m = (13 - 65) / (10 - 2) = -52 / 8 = -6.5
Therefore, the slope of the line is -6.5. This means that for every decrease of $6.50 in price, the quantity of almonds purchased increases by 1 pound.
Looking at the answer choices, we can see that the best description of the slope is almonds cost $6.50 per pound. Here option D is correct.
